How will the rending of the ammeter change if the key K is closed?

For the given circuit. Calculate reading of ammeter when key K is closed.

If the resistance R_(1) is increased (see figure), how will the reading of the ammeter and voltmeter change ?

If the resistance R_(1) is increased how will the reading of the ammeter and voltmeter change

In the given figure when the key is open the ammeter reading is 5 amp. What will be the ammeter reading when the key is closed

In the circuit in fig. If no current flows through the galvanometer when the key k is closed, the bridge is balanced. The balancing condition for bridge is

In the figure shown is a R-L circuit connected with a cell of emf epsilon through a key k. If key k is closed find the current drawn by the battery (a) just after the key k is closed (b) long after the key k is closed

A charged capacitor is allowed to dischare through a resistor by closing the key at the instant t=0 . At the instant t=(ln 4)mus , the reading of the ammeter falls half the initial vaslue. The resistance of the ammeter is equal to
