Question
Write and explain Kirchhoff's loop rule
✓
Answer
→Kirchhoff's loop rule : "The algebric sum of changes in potential around any closed loop involving resistors and cells in the loop is zero."
→Let us consider a closed path ABCDEA as shown in figure. →This circuit consists of resistors $R_1, R_2, R_3, R_4$, $R _5$ as well as batteries of $e m f s \varepsilon_1$ and $\varepsilon_2$ with negligible internal resistances.
