Question

A longer wire has more resistance than a shorter wire of the same thickness and same material.

• A. True
• B. False

Answer 1

The correct option is A True

We know that, resistance $R=\frac{\rho l}{A}$, where l is the length of the wire, A is the area of cross-section of the conductor and $\rho$ is the resistivity of the material.
Since the material and thickness is the same, it implies that both has the same cross-sectional area and resistivity.
Therefore with increase in length, the resistance of the material also increases.
