Draw a circuit diagram which includes the following : A battery of two cells, a bulb, an open switch.

In the circuit shown, the cell is deal. The coil has an inductance of 4H and zero resistance. F is a fuse of zero resistance and will blow when the current through it reaches 5 A . The switch is closed at t=0 . The fuse will blow:

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

In the circuit shown, find the value of resistance R in terms of inductance L and capacitance C such that the current through the cell remains constant forever after the switch is closed.

A capacitor C=100 muF is connected to three resistor each of resistance 1 kOmega and a battery of emf 9V . The switch S has been closed for long time so as to charge the capacitor. When switch S is opened, the capacitor discharges with time constant

Consider the potentiometer circuit for determining the internal resistance of a cell. When switch S is open, the balance point is found to be at 75 cm os the wire. When switch S is closed and value of R is 4 Omega , the balance points shifts to 60 cm . find the internal resistance of cell. .

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.

A 35.0 V battery with negligible internal resistance, a 50.0Omega resistor, and a 1.25 mH inductor with negligible resistance are all connected in series with an open switch. The switch is suddenly closed (a) How long after closing the switch will the current through the inductor reach one-half of its maximum value? (b) How long after closing the switch will the energy stored in the inductor reach one-half of its maximum value?
