In the given circuit diagram, which of the givedn switch (s)should be slosed, So that only the bulb A glows.

In which among the following circutis does the bulb glow?

In a simple circuit, why does the bulb glow when you close the switch ?

In a simple circuit, why does the bulb glow when you close the switch ?

An electric bulb is designed to consume 55 W when operated at 110 volts. It is connected to a 220 V, 50 Hz line through a choke coil in series. What should be the inductance of the coil for which the bulb gets correct voltage?

A ring is made of wire having a distance R_0 = 12Omega . Find the points A and B as shown in figure,at which a current carrying conductor should be connected so that the resistance R of the sub circuit between these points is equal to 8/3Omega

Shows a wire of length l which can slide on a U- shaped rail of negligible resistance. The resistance of the wire is R. The wire is pulled ot the right with a constant speed v. Draw an equivalent circuit diagram representing the induced emf by a battery. Find the current in the wire usingj this diagram.

Point masses m_1 and m_2 are placed at the opposite ends of a rigid rod of length L, and negligible mass . The position of point p on this rod through which the axis should p on this rod through which the axis should pass so that the work required to set the rod rotating with angular velocity omega_0 is minimum , is given by: .

Four light bulbs P, Q, R, S are connected in a circuit of unknown arrangement. When each bulb is removed one at a time and replaced, the following behavior is observed. Draw the circuit diagram for these bulbs.
