when key k is open

I is equal to 12/8 or 4/3 ampere
__________________

when key k is not open
I is equal to 12/4 ampere i.e. 3 A

this is by the V=IR formula
also series resistance is added whie parallel resistance is taken reciprocally and added then again inverted

e.g. 2 &4 r parallel
1/2+1/4= 3/4. so R = 4/3
