1) The bulb $B_2$ lights up earlier than $B_1$ and finally both the bulbs shine equally bright
2) $B_1$ light up earlier and finally both the bulbs acquire equal brightness
3) $B_2$ lights up earlier and finally B1 shines brighter than B2
4) $B_1$ and $B_2$ light up together with equal brightness all the time
Solution: Explanation: No Explanation
Self Inductance Mutual inductance Static EMI
