Which one of the following plots shows the variations of voltage in the coil [CBSE PMT 1994]
A)
B)
C)
D)
Correct Answer: B
Solution :
(1) For time interval 0 < t < T/2 \[I=kt,\] where k is the slope For inductor as we know, induced voltage \[V=-L\frac{di}{dt}\] \[\Rightarrow {{V}_{1}}=-KL\] (2) For time interval \[\frac{T}{2}<t<T\] \[I=-Kt\]\[\Rightarrow {{V}_{2}}=KL\]
