A constant current i is passed through a resistor. Taking the temperature coefficient of resistance into account, indicate which of the plots shown in figure best represents the rate of production of thermal energy in the resistor
Text Solution
Verified by ExpertsThe correct answer is:
D
Thermal energy in resistor is 
where 
⇒ ⇒ 
So 
With the time temperature increases, hence 
increases. This is best shown by curve .
