Answer 1

The rate of transfer of energy

Question 2

What is the simple formula for power in electrical circuits

Answer 2

P=VI

Question 3

What is the equation that shows power is the rate of transfer of energy

Answer 3

P=E/t

Question 4

We know that P=VI and V=IR, so what can we do with the two equations

Answer 4

Combine them to form 3 other ones
P=VI
P=V^2/R
P=I^2R
