WebbV1 - R1*I - V2 - R2*I = 0. Solving for current: I = (V1 - V2) / (R1 + R2) And so the potential difference across is R1 is V = R1*I = R1* (V1 - V2) / (R1 + R2). So the potential at a would be V1 - R1* (V1 - V2) / (R1 + R2). homework-and-exercises. electric-circuits. Share. Cite. WebbThe only way that I can think of is that the negative pole of the source is at − 10 V and since there is a potential difference of 0.7 V between the poles of the source, then the positive one must be at − 10 + 0.7 = − 9.3 V. I think that the presence of − 10 V and GND is that confused me. What would be the potential of GND here ?
