Q. When an electrical appliance is switched off, sparking occurs. Why?

Q. A circuit has a self-inductance of

1 H

and carries a current of

2 A

. To prevent sparking, when the circuit is switched off, a capacitor which can withstand

400 V

is used. The least capacitance of capacitor connected across the switch must be equal to

Q. Assertion :STATEMENT -1 : In an electric circuit containing an inductor, resistor, a switch and a cell in series, when the switch is opened long after it was closed, spark will not occur but spark may occur if the switch is closed long after it was opened Reason: STATEMENT - 2 : In the above situation the inductor in the circuit tends to maintain the situation that was present prior to changing the position of the switch and a spark is nothing but current through air.

Q. In the figure, the switch

S

is closed so that a current flows in the iron-core inductor which has inductance

L

and the resistance

R

. When the switch is opened, a spark is obtained in it at the contacts. The spark is due to
