Question:

The electric resistance depends on which of the following?

Options:

Length of the wire

Area of cross-section the wire

Resistivity of the wire

All of the above.

Correct Answer:

All of the above.

Explanation:

Expression for resistance : R

$R = \rho \frac{L}{A}$

L = length of the wire

A = area of cross section

$\rho$ = resistivity of the wire
