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 blow after how much time?
- Ajust after $t=0$
- Bafter $2s$
- Cafter $5s$
- Dafter $10s$
