A pure inductor `L`, a capactior `C` and a resistance `R` are connected across a battery of emf `E` and internal resistance `r` as shows in Fig. Switch `S_(W)` is closed at `t = 0`, select the correct altermative (S).

An inductor L and a resistance R are connected in series with a battery of emf E and a switch. Initially the switch is open. The switch is closed at an instant t = 0. Select the correct alternatives

An inductor L and a resistance R are connected in series with a battery of emf E and a switch. Initially the switch is open. The switch is closed at an instant t = 0. Select the correct alternatives

Plot a graph showing the variation of current 'T' versus resistance 'R', connected to a cell of emf E and internal resistance 'r'.

Both terminals of a battery of emf E and internal resistance r are grounded as shown. Select the correct alternative(s).

An inductor of inductance L = 8 H and a resistor of resistance R = 2Ω are connected in series with a battery of emf E = 10 V as shown in the figure. If the switch is closed at t = 0, then the voltage drop across the inductor at t = 1 s will be in volts)

A lead resistance R is connected across a cell of emf E and internal resistance r. If the closed circuit p.d. across the terminals of the cell is V the internal resistance of the cell is.

An inductor of inductance L and another resistor of resistance R are connected in series with a battery of emf E and a switch. Switch is closed at t = 0. How much charge will pass through the battery in one time constant? Internal resistance of the battery is negligible.
