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

In the circuit shown P ne R the reading of galvonometer is same switch S open or closed. Then

In the circuit shown above, when then switch S is closed,

In the circuit shown in figure the reading of ammeter is the same with both switches open as with both closed. Then find the resistance R . (ammeter is ideal).

In the potentiometer circuit shown in the figure the balance length AJ=60cm when switch S is open. When switch S is closed and the value of R= 5Omega , the b alance length AJ=50cm. The internal resistance of the cell C' is

In the circuit P != R, the reading of the galvanometer is same with switch S open or closed. Then

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_______.

In the circuit shown in the figure, reading of ammeter is I_1 when only S_1 is closed, reading of of ammeter is is I_2 when only S_2 is closed and reading of Ammeter,is I_3 when both S_1 and S_2 are closed then .
