Question

plzz help me I can,t put Kirchoff law
JEE main ​

Answer 1

Answer:

answer is option 2

Explanation:

No need to use kirchoffs law here .

we have to calculate current just after closing the key .

so inductor will provide infinite resistance and therefore no current will flow through inductor and 12 ohm resistor .

therefore total resistance of the circuit will be 10 ohm .

potential of the battery is given as 20 volt so current will be V/I = 20/10 =2 ampere.

hope it will help you ✌✌✌✌
