Question 23 of 209

The temperature dependence of resistance of $Cu$ and undoped $Si$ in the temperature range $300-400K$ is best described by

Alinear increase for $Cu$, exponential decrease for $Si$Blinear decrease for $Cu$, linear decrease for $Si$Clinear increase for $Cu$, linear increase for $Si$Dlinear increase for $Cu$, exponential increase for $Si$

Show answer and solution▾

Answer: (A) linear increase for $Cu$, exponential decrease for $Si$

Resistance variation with temperature: resistance of a metal increases with increase in temperature linearly and resistance of a semiconductor decreases exponentially with increase in temperature.
