Q. An alternating current i in an inductance coil varies with time according to the graph given below. Which one of the following graphs gives the variation of voltage with time?

In This post you will get answer of Q.
An alternating current i in an inductance coil varies with time according to the graph given below. Which one of the following graphs gives the variation of voltage with time?

Solution:

When the current increases the emf induced is $ V=+Lfrac{di}{dt}(say) $ ?…(i) When current decreases, emf induced is. $ V=-Lfrac{di}{dt} $ ?.(ii) The voltage induced changes This is shown in graph (c).
