A series circuit consists of three identical lamps connected to a battery as shown in Fig. 7.13 . when the switch S is closed, what happens (a) to the intensities of lamps A and B , (b) to the intensity of lamp C , ( c ) to the current in the circuit , and (d) to the voltage drop across the three lamps ? Does the power dissipated in the circuit increase, decrease, or remain the same ?

A circuit consists of three identical lamps connected to a battery as shown in the figure. When the switch S is closed then the intensities of lamps A and B

Two bulbs A and B are connected as shown . When switch 'S' is closed then which of them will fuse?

Three identical bulb are connected as shown in figure . When switch S is closed, the power consumed in bulb B is P . What will be the power consumed by the same bulb when switch S is opened ?

Figure shows three idenetical bulbs A,B and C connected to a battery of supply voltage V. When the switch S is closed, discuss the change is . (a) The illumination of the three bulbs (b) The power dissipated in the circuit .

Draw a circuit diagram when three bulbs are connected in series with a battery of cells, which are also connected in series.

Four identical bulbs each rated 100 watt, 220 volts are connected across a battery as shown. The total electric power consumed by the bulbs is:

B_(1), B_2 and B_3 are the three identical bulbs connected to a battery of steady emf with key K closed. What happens to the brightness of the bulbs B_(1) and B_(2) when the key is opened?

Three incandecent bulbs of 100 W each are connected in series in an electric circuit. In another circuit another set of three bulbs of the same wattage are connected in parallel to the same source. (a) Will the bulbs in the two circuits glow with the same brightness ? Justify your answer. (b) Now let one bulb in both the circuits get fused. Will the rest of the bulbs continue to glow in each circuit ? Give reason.

A resistor and an inductor are connected to an ac supply of 120 V and 50 Hz, the current in the circuit is 3 A. If the power consumed in the circuit is 108 W, then the resistance in the circuit is
