Resistivity of copper, nichrome and a semiconductor varies with temperature respectively as |
Linear, exponential increase and exponential decrease Exponential increase, linear and exponential decrease Exponential increase, exponential decrease and linear Linear, exponential decrease and exponential increase |
Exponential increase, linear and exponential decrease |
The correct answer is option (2) : Exponential increase, linear and exponential decrease For Copper $\to$ exponential increase For Nichrome $\to $ linear increase For Semiconductor $\to $ exponential decrease |
