(a) Define a circuit
(b) What does the deflection of a compass
needle shows?
(C) Why the bulb did not glow in the first
​

Answer 1

Answer:

a) The path for electricity to flow is called a circuit.

b) The deflection in the compass needle shows that the current is flowing through the circuit.

c) the bulb didn't glow in the first case because there wasn't enough current in the circuit for the bulb to glow. When one more cell was added, the current became strong and the bulb glowed.

Hope it helps
