Question

The average self-induced emf in a $$25 m H$$ solenoid when the current in it falls from $$0.2 A$$ to $$0 A$$ in $$0.01$$ second, is 


A
0.05V
loader
B
0.5V
loader
C
500V
loader
D
50V
loader

Solution

The correct option is B $$0.5 V$$
$$emf=L\dfrac { di }{ dt } $$
           $$=25\times { 10 }^{ -3 }\times \dfrac { 0.2 }{ 0.01 } $$
            $$= 0.5V$$
