how to find potential on a perticular point in d complex electric circuit??

perticularly whn resistors and capacitors both r connected

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;

V_AB=V_B-V_A=∑ε-∑i.R

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 "-".

V_AB=V_B-V_A= -ε₂-(+i.R₁+i.R₂)

V_CB=V_B-V_C= -ε₃-(-i.R₃)
