Three bulbs with their power and working voltage are connected as shown in the circuit diagram to a 12 V battery. The total power consumed by the bulbs is (ignore the internal resistance of the battery shown)

In the following circuit, 5 resistor develops 45 J/s due to current flowing through it. The power developed across 12W resistor is

Find out the value of current through 2 resistance for the given circuit

The charge developed on 4 F condenser is

For a cell, the graph between the p.d.(V) across the terminals of the cell and the current I drawn from the cell is shown in the fig. the emf and the internal resistance of the cell is E and r respectively

Equivalent resistance across A and B in the given circuit if r = 10 , R = 20 is

A part of circuit in steady state along with the currents flowing in the branches, the value of resistances is shown in figure. Calculate the energy stored in the capacitor

In the steady state, the energy stored in the capacitor is

In Wheat stone’s bridge shown in the adjoining figure galvanometer gives no deflection on pressing the key, the balance condition for the bridge is :

A current of 0.10 A flows through the 25 resistor represented in the diagram to the right. The current through the 80W resistor is:

In the circuit shown in figure, the potentials of B,C and D are :

The energy stored in the capcitor is

The vapour density of a gas is 11.2. The volume occupied by 11.2 g of this gas at N.T.P. is

The r.m.s velocity of hydrogen is  times the r.m.s. velocity of nitrogen. If T is the temperature of the gas,

The difference of  and its reciprocal is

So here the concept of reciprocals and reciprocating the numbers is used. It is basically comparable to flipping the number on its side. Here we were given the numberand the difference between this number and its reciprocal is 105/304.
