Q20Written answer

Boojho has a cell and a single piece of connecting wire. Without cutting the wire in two, will he be able to make the bulb glow? Explain with the help of a circuit diagram. 

Show solutionHide solution
Worked solution

Ans:  With the suggested configuration, he will be able to light the bulb. He can connect one of the bulb's terminals straight to the electric cell's negative terminal. As a result, he won't require any additional cable for our electric circuit. The diagram depicts the needed setup:

(i) What will be the direction of the current through the bulb in both cases? (Q to P or P to Q) 

(ii) Will the bulb glow in both cases?

(iii) Does the brightness of the glowing bulb depend on the direction of current through it? 

Show solutionHide solution
Worked solution

Ans: Current always flows from a battery's positive terminal to its negative terminal throughout the circuit. In the example of current flow from Q to P, current will flow from the positive terminal Q to the negative terminal P. Whereas, in the case of P to Q; current will flow from the negative terminal P to the positive terminal Q.

Ans: Because the current is flowing in both circumstances, the bulb will light up.

Ans: Whether the bulb glows brighter or duller depends on the circuit’s quantity of current and voltage. The direction of the current flow has no impact on it.

Q23Written answer

A torch is not functioning, though contact points in the torch are in working condition. What can be the possible reasons for this? Mention any three. 

Show solutionHide solution
Worked solution

Ans: The reason for the faulty functioning of the torch can be:

i. The cells may be disorganised.

ii. The filament of the bulb might be fractured, causing the bulb not to ignite.

iii. The cells may be depleted.

iv. The switch is defective.
