6.2.4 Energy Transfers (Green Topic)

Question 1

What are the units in the equation that links energy transferred, charge flow and potential difference?

Answer 1

Energy transferred (J)= Charge flow (C) x potential difference (V)

J= Joules
V= Volts
C= Coulombs

Question 2

What are the units for the equation that links power, potential difference and current?

Answer 2

Power (W)= Potential difference (V) x Current (A)

W= Watts
V= Volts
A= Amperes/Amps
