Question

Plz solve the que in the attachment..

Answer 1

total resistance = 1/4+1/4+1/2= 1+1+2/4=> 1ohm
we one that in parallel different current passes through each resistor so
i1= v/r1=>i1=4/4=1ampere
i2=4/4=1ampere
i3=4/2=2ampere
so I = 4 ampere

Answer 2

1/R(eff)=1/R1 +1/R2 +1/R3
(ii)1/R=1/4+1/4+1/2
1/R=1
R=1
I = V/R
    4/1
 =4A
