When three cells are connected in series, the total emf of the battery is 24 V Two resistors are connected in parallel with switches S, and S, as shown in the diagram below, and connected to the battery. An ammeter (A) reads the current passing through the battery and voltmeter(V) reads the potential difference across the 6 resistor. The cells and ammeter have negligible resistance. The voltmeter has a very high resistance. 24 V +1/1/1 A S1 60 S2 12 Ω 3.1 Calculate the emf of each cell. 3.2 Determine the reading on the voltmeter when switch S, is open. 3.3 Determine the reading on the voltmeter when S. is closed. 3.4 Determine the reading on the voltmeter when S, and S₂ are closed. 3.5 Calculate the equivalent resistance of the two resistors in parallel. 36 Calculate the reading on the ammeter when switches S. and Sz are closed (4) (2) (1) (1)​
