Text Solution

Verified by Experts
The correct answer is:
C

Kirchhoffs law states that, the algebraic sum of currents meet at a point (say junction) equals to zero i.e.,

Or i = i 1 = i 2 = i 3 In other words when a steady current flows through circuit, then neither accumulation of charges takes place at the junction in the circuit nor any charge is removed from there. Thats why Kirchhoffs first law

deals with the conservation of charge.
