Question

A thick wire has smaller resistance while a thin wire has larger resistance.

• A. True
• B. False

Answer 1

The correct option is A

True

According to the formula R = $\rho \frac{l}{a}$, resistance of a conductor is directly proportional to length 'l' of the conductor and inversely proportional to the area 'a' of the conductor.
The thick wire will have greater area and therefore it will have less resistance and will prove to be better conductor of electricity than a thin wire which will have higher resistance.
