Answer:

Correct Answer: 64. (a)

Solution:

  1. (a) We know from the Kirchhoff ’s first law that the algebraic sum of the current meeting at any junction in the circuit is zero (i.e. $\Sigma i=0$ ) or the total charge remains constant. Therefore, Kirchhoff’s first law at a junction deals with the conservation of charge.
