What is the equation that links power, potential difference and current?
Power = potential difference/current
Power = potential difference x current
Power = current/potential difference
Power = 0.5 x potential difference x current^2
which of the following is the correct equation that links power, energy transferred and time.
Power = time x energy transferred
Power x energy transferred = time
Power = energy transferred/time
Power = time/energy transferred
