Observing that the bulb does not glow in the circuit shown in the figure (A). Boojho changed the circuit as shown in figure (B). He observed deflection in the magnetic compass.
(a). What does the deflection in magnetic compass indicate?
(b). Why did the bulb not glow in figure (A)?
(c). What would be the effect of increase in the number of turns in the coil wound around the magnetic compass in figure (B)?
(d). What will be observed if the number of cells are increased in the circuit shown in figure (B)?
(b). Why did the bulb not glow in figure (A)?
(c). What would be the effect of increase in the number of turns in the coil wound around the magnetic compass in figure (B)?
(d). What will be observed if the number of cells are increased in the circuit shown in figure (B)?
(a). The deflection in the magnetic compass indicates that the .
(b). It's possible that the bulb didn't glow because of the following factors:
(c). The around the magnetic compass would increase as the number of turns in the coil looped around the magnetic compass increased, resulting in an in the magnetic compass deflection.
(d). The the number of cells increases.
