WORKING OF ELECTRIC SWITCH

ELECTRIC SWITCH

Fussing Of Bulb When It Is Switched On

In the circuit shown all the ammeters are ideal. (a), If the switch S is open, find the reading of all ammeters and the potential difference across the switch. (b) If the switch S is closed, find the current through all ammeters and the switch also.

shows three resistances are connected with switch S initially the switch is open. When the switch S is closed find the current passed through it.

Assertion: The probability of an electric bulb fusing is higher at the time of switching ON and OFF . Reason: Inductive effects produce a surge at the time of switch OFF and switch ON .

In the circuit shown in the figure, intially SW is open. When the switch is closed, the charge passing through the switch in the direction_________to_______.

The circuit was in the shown state from a long time. Now the switch S is closed. The charged that flows through the switch is
