Question

What is amperage, and what is its relationship to voltage and power?

Answer 1

Amperage is the rate of electrical charge per time.

1 amp = 1 coulomb / second

Power is the product of amperage and voltage.

P = IV

Answer 2

P = i V

Step-by-step explanation:

Electrical power is the rate of work done against electrical forces

So we know that here in electrical circuits the work done to move the charge from initial to final position is given as

`W = q\Delta V`

so here we need to find the electrical power

so it is given as

`P = (dW)/(dt)`

`P = (dq)/(dt) \Delta V`

we know that rate of flow of charge is electric current

`(dq)/(dt) = i`

so we have

P = i V
