| A charge passing through a resistor is varying with time as shown in the figure. The amount of heat generated in time 't' is best represented (as a function of time) by: |
 |
A)
B)
C)
D)
Correct Answer: C
Solution :
\[i=\frac{dq}{dt}=\] slope of \[q-1\,\,\text{graph}\]\[=-\,5\](which is constant) Amount of heat generated in time t \[={{i}^{2}}RT\]\[\propto \,\,t.\]
