For the given circuit. Calculate reading of ammeter when key K is closed.

Find time constant of the circuit when (a) S is closed . (b) S is open.

In the circuit shown, when switch S_(1) is closed and S_(2) is open, the ideal voltmeter shows a reaiding of 18 V . When switch S_(2) is closed and S_(1) is open, the reading of voltmeter is 24 V . When S_(1) and S_(2) both are closed, the voltmeter reading will be

The galvanometer deflection , when key K_(1) is closed but K_(2) is open equals theta_(0) (see figure ) On closing k_(2) also and adjusting R_(2) to 5Omega , the deflection in galvanometer becomes (theta_(0))/(5) the resistnce of the galvanometer is then , given by [Neglect the internal resistance of battery]:
