In the circuit shown in figure:
Would any of the bulb glow when the switch is in the'OFF' position?

In the circuit shown in figure: What will be the order in which the bulbs A, B and C will glow when the switch is moved to the 'ON' position?

Draw in your notebook the symbols to represent the following components of electrical circuits: connecting wires, switch in the 'OFF' position, bulb, cell, switch in the 'ON' position and battery.

For the circuit shown here, would the balancing length increse, decrease or remain the same, if (i) R_(1) is decreased: (ii) R _(2) is increased , without any other change, (in each case) in the rest of the circuit. Justify your answers in each case.

In the circuit as shown in figure , the heat produced by 6 Omega resistance due to current flowing in it is 60 calorie per second. Calculate the heat produced across 3 Omega resistance per second in calories is :
