You may be surprised to hear that the amount of current that passes through a conductor depends not only on its resistance but also on how many volts are applied to it.
In other words, if you were to put a 100mA load across two resistors and then measure their voltage difference, there would probably be an error in measurement, because the lower resistor will draw less than 100 mA. But when measuring the same circuit using 1V instead of 0.01 V, the voltmeter would read a much higher reading for both resistors. Click more now
This means that you need to take into account the amperage rating of your components before using them in high-current circuits. This is especially true if you’re building a product that requires lots of power.
The term “amperes” is used to describe this relationship between current and voltage. It refers to the number of milliamperes (m) of electricity passing through a certain volume (A), so an amp is the SI unit for electric current.
Ampère's law is a fundamental property of electrical conductors, stating that the magnitude of the electromotive force or potential difference is proportional to the rate at which charges flow. It states that the rate of change in magnetic flux over time is equal to the sum of the rates of change of the currents around each loop.
When current flows through a conductor like a wire, it causes a magnetic field. When two loops of wire carry different amounts of current, they create opposing fields. If one loop carries twice as much current as the other, then the total field created by all the wires is double the strength.
Current flows from positive to negative. Therefore, if we have a closed loop carrying a given amount of charge, the direction of the current and therefore the polarity of the field must be consistent.
If the closed loop is formed of two paths that are identical but opposite in direction, the net result will cancel out. In this case, the current in each path is half of what it was originally.
Therefore: The magnitude of the induced EMF is directly proportional to the number of amps flowing through the conductor. That means that an increase in the number of amps going through the wire corresponds with greater ampere-turns. A greater number of turns is generally associated with a higher current capacity.

If you're wondering how much electricity it takes to power a light bulb, you might be interested in knowing that the answer is very little. In fact, most lights don't use any more energy than a regular incandescent bulb.
That's why you should always turn off your lights when you leave a room. The average household uses roughly 100 watts of energy per hour. So, turning on the light switch will save you money and help the environment at the same time.

I am trying to set a default value for a textbox.
My code is:
But I want to know how to access the "value" of the text box.
Thanks.
A:
You can do it with $scope.$apply() and.val():
$scope.setDefault = function(obj) {
obj.defaultValue = 'foo';
};

The amper (Amperes) is a unit of measurement that measures electrical current. One Amp is equal to 0.01 Watts.
Current is measured in amps and volts. The current is always positive – it flows from the source to the load or sinks. Voltage is measured in Volts and is always negative. In electronics, power is used when describing the flow of energy. Power is voltage multiplied by current.
A volt is an electric potential difference of one volt equals 1 Joule per second. A Joule is a measure of the work required to move one Coulomb of charge through a conductor.
An amp is a standard unit of current. It is named after André-Marie Ampère, who was a 19th-century French physicist. He developed many important theories related to electromagnetism. Today, the SI system of units is in wide use throughout science. This means that scientists around the world agree on using one symbol to represent each dimensionless quantity. These quantities can then be combined to give new numbers that describe physical phenomena.
The world has entered a new age with the emergence of smartphones. The smartphone is the future as it not only connects us to the outside but also to each other. As everyone is busy in their daily life so they don’t have time to connect with friends and family, here ampere is the solution to this problem which lets people stay connected with others at any place using voice or video calls.
The smartphone is the device that helps users in connecting with the world, without a doubt there are many apps available in app stores but all these apps have some drawbacks like heavy data consumption, low battery backup, and lack of social networking features.
Ampere was launched by the same company that developed the concept of Bleep which was recently bought out by Google for $12 billion. In 2017 the CEO and founder of the company, Jyoti Bansal sold his shares in the company for around $70 million.
Features of Ampere:
The first thing I want to tell you about the feature is the security. The developers have made sure that the calls on this application will be secure and private, no one will listen to your conversation unless you give permission. This is the best part of the application as most of the apps don’t allow the user to share their conversations.
Another major point is its speed. There are thousands of applications in the play store and apple store that provide similar services but none of them can beat Ampere when it comes to performance. It is the fastest calling application that not only allows voice communication but also text messaging. The user doesn’t need to worry about the network because the call quality is always good with this app.
There is a wide range of options available in the menu bar and this is the reason why this app has become the first choice for all people. You don’t need to install any additional apps in order to use the app, it works from the main screen itself.
Ampere is available for Android and iOS devices. If you are using an android device then the installation process will take around 5 minutes, if you are using an iPhone then it takes 1 minute.
Conclusion:
Ampere was created by the same company that was behind Bleep which was later bought by Google for $12 billion. This shows that there is some serious competition in the market and the apps have to work harder than ever before to survive in such a crowded market.
Conclusion
The Ampere, discovered by André-Marie Ampère, was the first fundamental unit to describe electric current in terms of magnetic flux and was defined as a quantity of magnetic flux passing through a surface element per second. It's named after him. However, he didn't define it. So it took another guy, William Thomson, to do that. Here's how we did it in our class.
Benefits
The Ampere is a unit of current and flow, similar to an ampere of electricity. It can help explain how electrical currents interact with each other as well as how they affect the surrounding environment. There are two types of Amperage: Alternating Current (AC) and Direct Current (DC). AC and DC currents have different properties that make them unique. A common example of this difference would be the way that appliances operate. When connected to a regular household power outlet, most modern electronics, such as computers, televisions, speakers, phones, and lights use alternating currents.

Drawbacks
One of the disadvantages of using amperes instead of voltage is that there is no standardization between different countries' power outlets. This means that the number of amps required for any given device may differ depending on where you live, making it difficult to purchase electrical devices internationally. It also makes measuring current more complicated as well, as you need a separate meter for each country's wall sockets.

FAQ
1. Does amperage mean anything? The unit of measurement for the amount of current (electricity) flowing through a circuit is called an amp. For example, when you plug your iPod into the wall, the wall socket delivers 120 volts to the wire inside the earbuds. This means that the wire carries 2 amps of electricity.
2. How does "amper" come from? Amp comes from the word "ampère," which was originally the French term for the English letter “A”. The letter symbolizes the number one, so the abbreviation for the letter is AMP.
3. Is there a different meaning for each type? Yes. You can find more information here:
4. How did it start getting used? The first use of the word ‘ampere' by itself appeared in 1801, according to the Oxford English Dictionary. In the early 1800s, people were using units such as the volt, milliampere hour, and even ampere-hour. But they weren't really measuring electrical quantities.
5. Why didn't we have this until now? One reason is that our understanding of electricity has been limited. Another reason is that the word "ampère" had already become part of a proper name; it's where the term 'ampere meter' came from.
6. What are some of its applications? The most common application for the ampere is in power transmission and distribution, but you'll also see them used to measure the flow of electric current.
7. How do I know what a certain voltage or amp is? You need to understand how the circuit works before you can determine the correct unit of measurement. For example, if your iPod charger uses 120 volts, then that means the wire inside the earbuds will carry 2 amps.
