Answer» Question 23

Observing that the bulb does not glow in the circuit shown in Fig 1, Boojho changed the circuit as shown in Fig 2. He observed deflection in the magnetic compass.



(i) What does the deflection of magnetic compass indicate?

(ii) Why did the bulb not glow in Fig. 1?

(iii) What would be the effect of increase in the number of turns in the coil wound around the magnetic compass in Fig. 2?

(iv) What will be observed if the number of cells is increased in the circuit shown in Fig. 2?
