Dear student,

Potential difference between two points in circuit is the energy lost by the charge in being transferred from one point to another. For example, potential difference between A and B is found with following formula;



This formula shows the energy lost by charge moving from point A to point B.

If the direction of the current and current passing through the resistor are the same then we take i.R as "+", if they are in opposite directions then we take i.R as "-".

VAB=VB-VA= -ε2-(+i.R1+i.R2)

VCB=VB-VC= -ε3-(-i.R3)
