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

Options

A. conservation of energy
B. conservation of electric charge and energy respectively
C. conservation of electric charge
D. conservation of energy and electric change respectively

Answer

B

Explanation

(b) Kirchoff's first law is junction rule, according to which the algebraic sum of the currents into any junction in zero. The junction rule is based on conservation of electric charge. Kirchhoff's second law is loop rule according to which the algebraic sum of the potential difference in any loop including those of the potential difference in any loop including those associated emfs. and those of resistive elements must equal zero.
This law is basically the law conservation of energy.
