It measures the rate of flow of electric charge flow through the conductor. It is represented by the symbol A. One ampere is equal to the one coulomb of charge which is mathematically equal to the 6.
Thanks for the information… I hope you guys can also help us with the calculation with units of this topic. Your email address will not be published.

Amps are the water pressure running through the hose, and volts are the diameter of the hose.
Watts would be the volume of water coming out of the hose. In the US, all residential homes are wired with a voltage circuit for all minor electrical appliances such as coffee makers and table lamps , and a voltage circuit for major appliances like your clothes dryer, stove, and air-conditioning unit. Think of your major appliances as needing more power, so they require a larger "pipe" through which to operate.
Keep this concept in mind when operating multiple appliances on the same circuit of your home's outlet system. In newer homes, a wiring circuit's general layout will typically be written alongside each circuit breaker on your circuit panel. For example, in a home built after , each breaker is associated with a certain zone of a house — that is, kitchen and bath on one, bedrooms on another, etc.

Water — Charges or electrons that constitutes the current flow. Water flow in each smaller pipes — Can be compared to current.
Rate of current flow — Amperes. Leave a Reply Cancel reply Comment. The same is true of an electrical system: Increasing the voltage will make more current flow. Let's say you increase the diameter of the hose and all of the fittings to the tank. You probably guessed that this also makes more water come out of the hose.
This is like decreasing the resistance in an electrical system, which increases the current flow. Electrical power is measured in watts. In an electrical system power P is equal to the voltage multiplied by the current. The water analogy still applies. Take a hose and point it at a waterwheel like the ones that were used to turn grinding stones in watermills. You can increase the power generated by the waterwheel in two ways. If you increase the pressure of the water coming out of the hose, it hits the waterwheel with a lot more force and the wheel turns faster, generating more power.
If you increase the flow rate, the waterwheel turns faster because of the weight of the extra water hitting it. In an electrical system, increasing either the current or the voltage will result in higher power. Let's say you have a system with a 6-volt light bulb hooked up to a 6-volt battery. The power output of the light bulb is watts.
