A sinusoidal voltage Vsin(at) is applied across a series combination of resistance R and inductor L. The amplitude of the current in the circuit is

You are given several identical resisters each of value 5Omega and each capable of carrying a maximum current of 2A. It is required to make a suitable combination of these resistance to produce a resistance of 2.5Omega which can carry current of 4A. The minimum number of resistances required for this job is

The galvanometer shown in the figure has resistance 10Omega. It is shunted by a series combination of a resistance S = 1Omega and an ideal cell of emf 2 V. A current 2 A passes as shown.

The resistance of a series combination of the resistance is S. when they are joined in parallel equvalent resistance is P. Find the value of ((S)/(2P))

An alternating current source of frequency 100 Hz is joined to a combination of a resistance, a capacitance and a coil in series. The potential difference across the coil, the resistance and the capacitor is 46, 8 and 40 volt respectively. The electromotive force of alternating current source in volt is

The resistance of the series combination of two resistances is S. When they are joined in parallel the total resistance is P. If S= nP then the minimum possible value of n is

The resistance of the series combination of two resistances is S. When they are joined in parallel the total resistance is P. If S= nP then the minimum possible value of n is
