In the circuit shown in the figure, reading of voltmeter is V1 when only S1 is closed, V2 when only S2 is closed and V3 when both S1 and S2 are closed. Choose the correct relation between V1, V2 and V3.
One mole of diatomic gas is taken through a cyclic process. Pressure, volume and temperature of gas at A is P0, V0 and T0. List-I gives some physical quantities and List-II gives their possible magnitudes.
