◉ 01.2. Which equation links energy transferred (E), power (P) and time
(t)?


A) energy transferred = power/time
B) energy transferred = time/power
C) energy transferred = power x time
D) energy transferred = power^2 x time
Answer: C


◉ 01.3. The battery in the electric car can store 162 000 000 J of energy.
The charging station has a power output of 7200 W.
Calculate the time taken to fully recharge the battery from zero.
Answer: E = p x t
162 000 000 = 7200 x t
t = 162 000 000/7200
t = 22500

, ◉ 01.4. Which equation links current (I), potential difference (V) and
resistance (R)?


A) I = V x R
B) I = V^2 x R
C) R = I x V
D) V = I x R
Answer: D


◉ 01.5. The potential difference across the battery is 480 V.
There is a current of 15 A in the circuit connecting the battery to the
motor of the electric car.
Calculate the resistance of the motor.
Answer: V = I R
R = V/I
R = 480/15
R = 32


◉ 01.6. Different charging systems use different electrical currents.
• Charging system A has a current of 13 A.
• Charging system B has a current of 26 A.
• The potential difference of both charging systems is 230 V.
