P2 : Potential difference, power and energy

Question 1

Potential difference

Answer 1

The difference in the amount of energy that charge carries have between two points in a circuit

Question 2

What is the equation for potential difference

Answer 2

E = Q x v
E = energy in Joules (J)
Q = Charge in coulombs (C)
V = Potential difference in volts (V)

Question 3

Power

Answer 3

A measure of how quickly energy is transferred from one form to another.
P = E/T
