Answer 1

Value of I will be 7 A (option C)

• In the 1st branch , 4A and 5A will be added to give 9A.

• From that branch , 1A is getting out and 2A is getting in. So , net current will be 9-1+2 = 10A.

• Again, that 10A current is getting terminated to give 3A and I .

So, we can say :

$I + 3 = 10$

$\implies I = 10 - 3$

$\implies I = 7 \: Ampere$

So, value of I is 7 ampere.
