Vedclass · Answer

(D) Kirchhoff's first law,also known as the Junction Rule or Current Law $(KCL)$,states that the algebraic sum of currents meeting at a junction is zero $(\Sigma i = 0)$. 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 or Voltage Law $(KVL)$,states that the algebraic sum of potential differences around any closed loop is zero $(\Sigma iR = \Sigma E)$. 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 $(\Sigma i = 0)$ and second law $(\Sigma iR = \Sigma E)$ are based on which of the following respectively? (Where the symbols have their usual meanings.)
