Question

(i) What will be the direction of the current through the bulb A

(ii) What will be the direction of the
current through the bulb B

(iii) Will the bulb glow in both the cases?​

Answer 1

Answer:

1. Current always flows from positive terminal of a battery to negative battery through the whole circuit. In case of Q to P, current will flow from positive terminal Q to negative terminal P. In case of P to Q, current will flow from negative terminal P to positive terminal Q.

2. In case of Q to P, current will flow from positive terminal Q to negative terminal P. In case of P to Q, current will flow from negative terminal P to positive terminal Q. (ii) Current is flowing in both the cases so the bulb will glow in both the cases. ... It is not affected by direction of current flow.

3. Yes, the bulb will glow in both the cases as the circuit is complete in both the cases.

Answer 2

(I) forward to bulb
(II)backward to bulb
(III) yes
