An inductor is connected to a battery through a switch. Explain why the emf induced in the inductor is much larger when the switch is opened as compared to the emf induced when the switch is closed.

An inductor is connected to a battery through a switch. The emf induced in the inductor is much larger when the switch is opened as compared to the emf induced when the switch is closed. Is this statement true or false?

An inductor is connected to a direct voltage source through a switch. Now

Find current through battery when switch is closed.

Current through the battery at the instance when the switch S is closed is

A coil of self-inductance 15 H is connected to a battery of 10 V through a 5 Omega resistor and a switch. The switch is suddenly opened in 2 ms. Calculate the average emf induced in the coil.

In the circuit shown, the reading of ammeter when switch S is open and when switch S is closed respectively are

The connections shown in figure are established with the switch S open. How much charge will flow through the switch if it is closed ? .

An inductor L , a resistanece R and two identical bulbs, B_(1) and B_(2) are connected to a battery through a switch S as shown in the figure. The resistance R is the samem as that of the coil that makes L .Which of the following statement gives the correct description of the happenings when the switch S is closed

A 4mu F capacitor is connected to a battery of emf 24V. Through a resistance of 5 M Omega and a switch which is kept open initially. Internal resistance of the battery is negligible. Switch is closed at t=0. Potential difference across capacitor and resistor at t=0 are respectively.
