Question
State Kirchhoff's rules. Explain briefly how these rules are justified.
✓
Answer
Junction rule: At any junction, the sum of the currents entering the junction is equal to the sum of currents leaving the junction.
Loop rule: The Algebraic sum of changes in the potential around any closed loop involving resistors and cells in the loop is zero.
Alternate Answer
$\sum\text{i} = 0 $ Justification: Conservation of charge.Loop rule: The Algebraic sum of changes in the potential around any closed loop involving resistors and cells in the loop is zero.
Alternate Answer
$\sumΔ \text{V} =0,$ where Δ V is the changes in potential. Justification: Conservation of energy.Need a full question paper?
