The current ' (i ) ' in an inductance coil varies with time ' (t ) ' according to following graph Which one of the following plots shows the variations of voltage in the coil?

Step-by-step solution

(1) For time interval (0 < t < T / 2 ) (I=k t ), where (k ) is the slope For inductor as we know, induced voltage (V=-L d i d t ) ( V₁=-K L ) (2) For time interval ( T 2 < t < T ) (I=-K t V₂=K L )
