How do you calculate power in math?

Answer 1

Power is defined as the work done per unit time and work is defined as the amount of energy transferred by a force over a distance. Through a series of conversions it can also be shown that the power of an electrical circuit component is equal to its voltage multiplied by the current passing through it.

Answer 2

For DC circuits, KW = Volts times Amps divided by 1000. For AC circuits, KW = Volts times Amps Times PF (power factor) divided by 1000.

Answer 3

Only scientific calculators have a "power" key. There is usually some key labelled something like xy. To calculate 2 to the power 10, press 2, then xy, then 10.

Answer 4

p= ei

power = voltage times current
