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
