An inductor is connected to a battery through a switch. Explain why the emf induced in the inductor is much larger when the swithc 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

An inductor L is allowed to discharge through capacitor C. The emf induced across the inductance when the capacitor is fully charged is

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

An inductor L and a resistor R are connected in series to a battery, through a key/switch. Show graphically, how current decreases with time when the key/switch is opened.

A circuit consists of three identical lamps connected to a battery as shown in the figure. When the switch S is closed then the intensities of lamps A and B

When the switch is closed find the charge flown through switch?

An inductor of 10mH is connected to a 18V battery through a resistor of 10k Omega and a switch After a long time, when the maximum current is set up in the circuit, the current is switched off. Calculate the cur- rent in the circuit after 2 mu s.

Steady state current through the resistor of resistance 4 Omega when both switches are closed, as compared to the current when both switches are open , is

Figure shows an inductor L and a resistor R connected in parallel to a battery through a switch. The resistance R is the same as that of the coil L. Two identical bulbs are put in each arm of the circuit? (i) Which of the bulb lights up earlier when switch S is closed? (ii) Will the bulbs be equally bright after some time?
