Recall and use the equations: P = I V and E = I V t. You might need to know these two equations for the exam. First one is: P= IV (Unit: Watts) P is power, I is Electric Current (measured in Amps), and V is Potential difference (Voltage, measured in Volts). Units for power is Watts. This is also known as Joule’s Law. The second one is E= I V t (Units: Joules) E= Energy I= Electric Current t= time (sec)
