PhysicsEasysingle choice

Variation of resistance of the conductor with temperature is as shown. Temperature coefficient of the conductor is

Options:

Answer:

Solution:

$R_{t} = R_{0} (1 + α Δ t)$

Where $α$ is temperature coefficient of conductor

$= R_{0} + R_{0} α Δ T$

Slope of graph $m = R_{0} α$

$∴ α = \frac{m}{R_{0}}$
