Ya Rishi is right.

I=(12-9)/150= 0.02mA

let 9V as GND then Potential at B= (47+27)K * 0.02mA =1.48V

so pot. at B if GND is 0V =9V+1.48V =10.48V

Please Explain how the voltage of these batteries adding?

Atif said:   1 decade ago
The batteries are connected in series opposing configuration, Then how voltages can b add?

Here the net voltage should be 12-9 or 9-12. Why.

Because both the facing polarities are same.

I=21/150
V1=74*21/150
V2=76*21/150
V at B=(V1+V2)/2=10.5
