Vedclass · Answer

(A) Kirchhoff's first law,also known as the Junction Rule,states that the algebraic sum of currents meeting at a junction is zero. This is a direct consequence of the law of conservation of charge,as charge cannot accumulate at a junction.Kirchhoff's second law,also known as the Loop Rule,states that the algebraic sum of potential differences in any closed loop is zero. This is a direct consequence of the law of conservation of energy,as the work done in moving a unit charge around a closed loop in an electrostatic field is zero.

Kirchhoff's first law $(\sum i = 0)$ and second law $(\sum iR = \sum E)$,where the symbols have their usual meanings,are respectively based on:
