NEET 2006 Physics question

Kirchhoff's first and second laws for electrical circuits are consequences of:-

(1)Conservation of energy
(2)Conservation of electric charge and energy respectivelyCorrect
(3)Conservation of electric charge
(4)Conservation of energy and electric charge respectively

Answer: (2)

Solution

Kirchhoff's first (junction) law says the algebraic sum of currents at a junction is zero, which expresses conservation of electric charge. Kirchhoff's second (loop) law says the algebraic sum of potential differences around a
