The current I in an inductance coil varies with time according to the graph given in the figure. Which one of the following graphs gives the variation of voltage with time across the inductor?

Step-by-step solution

The voltage across an inductor is V = - L d i d t So the voltage across the inductor will always be opposite to the rate of change of current. When d i d t > 0 then V < 0 and vice versa Also, the magnitude of V is proportional to the magnitude of d i d t . When d i d t decreases, V also decreases
