A) 1.0A
B) \[\frac{4}{3}\text{A}\]
C) \[\frac{\text{3}}{\text{4}}\text{A}\]
D) \[\frac{3}{40}\text{A}\]
Correct Answer: D
Solution :
EMF induced, \[e=-L\frac{\Delta i}{\Delta t}\] \[=-60\times {{10}^{-3}}\times \left( \frac{1.5-1}{0.1} \right)\] \[=0.3\,volt\] \[\therefore \]Current induced, \[i=\frac{e}{R}=\frac{0.3}{4}=\frac{3}{40}A\]You need to login to perform this action.
