Questions 16 – 20 are based on the passage and diagram below.

If the voltage of the battery was known, and there was a resistive load of 1 Ohm placed in the series, the current would be

Or, if the voltage and the current are known, then it is possible to calculate the amount of resistance in the circuit.

R = V ÷ I
R = 12 ÷ 12
R = 1 O
