Physics Question on Current electricity

Question

Kirchhoff's first law, i.e. $\sum i =0$ at a junction, deals with the conservation of

Answer 1

Solution

The principle of conservation of electric charge implies that: at any node (junction) in an electrical circuit , the sum of currents flowing into that node is equal to the sum of currents flowing out of that node. This is known as Kirchhoff's current law.
