Question
In the circuit shown, the cell is ideal. the coil has an inductance of 4H and zero resistance. F is a fuse of zero resistance and will blow when the current through it reaches 5A. The switch is closed at t = 0. The fuse will below :
Options
A.just after t = 0
B.after 2s
C.after 5s
D.after 10s
⇒ 2 = 
⇒ ᐃt = 10 secMore ElectroMagnetic Induction Questions
