Q:

# How many amperes of power, or amps, does a computer draw?

A:

Depending on the type of computer used, the amps drawn range from 0.25 to more than 2. Laptop computers are at the low end of that range, and desktop machines draw the most power.

Amperes measure power use, but watts are the more common designation for power consumption in electronics. The label used to show how many watts an item is anticipated to use is shown with the number followed by a W.

Amps are simply derived from this number using a calculator. If the power outlet used is 120 volts, divide the device's the number of rated watts by 120. The amp rating is very is helpful at calculating how many devices can be on a circuit. If the circuit rating is known, add all the amp ratings to learn whether expected power usage is greater than the amount that the circuit can handle.

In order to convert amps, short for amperes, into kVA (Kilovolt-ampere), current in amps and the voltage in volts has to be multiplied and then divided by 1000. Mathematically, kVA = Current (in amp) * Voltage (in volts) / 1000.
