R = 47+27+56+2 = 150*10^3.
V = IR.
I = V/R = (12-9)/150*10^3 = 20*10^-6.
V = IR.
I = V/R = (12-9)/150*10^3 = 20*10^-6.

Veff = 12-9 = 3V
RT = 150 K
I=Veff/RT
I = (3/150)x10^-3
I =(1/5)x10^-4
I = 20x10^-6 = 20uA
RT = 150 K
I=Veff/RT
I = (3/150)x10^-3
I =(1/5)x10^-4
I = 20x10^-6 = 20uA

Using kirchaff's law,In the circuit the current remains same. So, take it as I,
9-(47k+27k+56k+20k)*I-12=0
9-12-(150k)*I=0;
150K*I=3;
I=3/150K;
I(current) = 20 micro amps.
9-(47k+27k+56k+20k)*I-12=0
9-12-(150k)*I=0;
150K*I=3;
I=3/150K;
I(current) = 20 micro amps.
