The potential difference across a 2-H inductor as a function of time is shown in Fig. At time `t = 0`, current is zero. Area under `V_(L) - t` graph givesA. currentB. change in currentC. product of inductance and currentD. product of inductance and change in current |

Answer» Correct Answer - D Since `V_(L)=(Ldi)/(dt)` `Ldi=V_(L)dt` Integrating `Lint di = int V_(L) dt` `L_(i_(f)-i_(i))= int_(0)^(t) V_(L)dt` = area under `V_(L)-t` graph. |
