Answer 2

Calculating energy transferred

For a given amount of electrical charge that moves, the amount of energy transferred increases as the potential difference increases.

You can work out the energy transferred using this equation:

energy transferred = potential difference × charge

E = V × Q

where:

E is the energy transferred in joules, J

V is the potential difference in volts, V

Q is the charge in coulombs, C

Question

How much energy is transferred when the potential difference is 120 V and the charge is 2 C?

Energy transferred = 120 × 2 = 240 J

This equation can be rearranged to V = E ÷ Q

So voltage is energy transferred divided by charge. The rearranged formula means we can define one volt as one joule per coulomb
