Figure-5.362 shows a circuit in which an inductor of 5H is a=connected to a 20V battery and a fuse of rating 30A. Neglect any resitance in the circuit, if switch is closed at t=0 find the time after which fuse will blow up.

In the circuit as shown in figure the switch is closed at t = 0 . A long time after closing the switch

An uncharged capacitor of capacitance C is connected with a battery of EMF V and a resistance R. The switch is closed at t=0 . The time instant at which the current in the circuit is (V)/(4R) is t=

In the circuit shown the cell is ideal. The codil has an inductance of 2H and will blow when the current through it reaches 5a. The switch is closed at t=0. Find the time (in second)n when fuse will blow.

An inductor of 0.5 H is connected across a 100 V, 50 Hz supply. The reactance of the circuit is

In the circuit shown in figure switch S is closed at time t=0 Current I from the battery at time t is given by

In adjacent circuit, switch S is closed at t = 0. The time at which current in the circuit becomes half of the steady current is

Figure-5.102 shows a RL circuit. If at t-0 switch is closed, find the current in inductor as a function of time.

In the circuit shown, the cell is deal. The coil has an inductance of 4H and zero resistance. F is a fuse of zero resistance and will blow when the current through it reaches 5 A . The switch is closed at t=0 . The fuse will blow:

In the circuit shows Fig the cell is ideal. The coil has an inductance of 4 H and zero resistance. F is a fuse of zero resistance and will blow when the current through it reaches 5 H . The switch is closed at t= 0 . The fuse will blow
