State the Kirchhoff's rules used in electric networks. How are these rules justified ? |
|
Answer» Solution :STATEMENT of Kirchhoff's laws Justification. Junction Rule: At any junction, the sum of currents, entering the junction, is equal to the sum of currents leaving the junction. Loop Rule: The algebraic sum of changes, in potential, AROUND any closed loop INVOLVING resistors and cells, in the loop is zero. `Sigma(DeltaV)=0` Justification: The first law is in accord with the law of conservation of charge SEconds law is in accord with the law of conservation of energy. |
