The diagram shows two resistors, P and Q, in series. The ammeter reads 0.20 A. Voltmeter X reads 1.2 V and voltmeter Y reads 2.0 V.
Calculate the potential difference across resistor P.
Answer explanation
Voltmeter Y is measuring voltage for both resistors = 2.0 V
Voltmeter X is measuring voltage for resistor Q only = 1.2 V
