In the given figure switches `S_(1) and S_(2)` are in open condition. The resistance across ab when the switches `S_(1) and S_(2)` are closed is ……………… `Omega`.

In the given ciruit Ammeter reading is same when both switches S_(1),S_(2) are closed or opened. The value of resistance R is

The resistors R_(1),R_(2),R_(3) and R_(4) are connected as shown in the figure. S_(1) and S_(2) are two switches . Discuss the flow of current through the resistors when (1) S_(1) and S_(2) both are closed. (2) S_(1) and S_(2) both are open. (3) S_(1) is closed and S_(2) in open.

In the given circuit, the initial charges on the capacitors are shown in the figure. The charge flown through the switches S_(1) and S_(2) respectively after closing the switches are

In the circuit shown in the figure, if switches S_(1) and S_(2) have been closed for a long time, then charge on the capacitor.

In the circuit shows (Fig.) switches S_(1) and S_(3) have been closed for 1 s and S_(2) remained open. Just after 1 s , switch S_(2) is closed and S_(1) and S_(3) are opened. Find after that instant (t = 0) : the maximum charge on the capacitor

In the circuit shows (Fig.) switches S_(1) and S_(3) have been closed for 1 s and S_(2) remained open. Just after 1 s , switch S_(2) is closed and S_(1) and S_(3) are opened. Find after that instant (t = 0) : the maximum current in the circuit containing inductor and capacitor (only S_(2) is closed)

In the circuit shows (Fig.) switches S_(1) and S_(3) have been closed for 1 s and S_(2) remained open. Just after 1 s , switch S_(2) is closed and S_(1) and S_(3) are opened. Find after that instant (t = 0) : the charge on the upper plate of the capacitor as a funtion of time
