Question

The length of the wire is doubled. Its conductance will, remain unchanged, be halved, be doubled, be quadrupled

MARKS App · Accepted Answer

The inverse of resistance of any wire or conductor is defined as conductance.

conductance $G = \frac{1}{R}$

Resistance of a wire is given by

$R = \frac{ρ L}{A}$

Here, $ρ =$ Resistivity of wire,

$L =$ Length of the wire,

$A =$ Cross-sectional area.

If the length of the wire is doubled, the resistance will also get doubled.

thus the conductance of the wire will be halved.
