Which among the following is true?

(a) According to Kirchhoff’s law, the current flowing towards a junction is equal to the voltage drop

(b) According to Kirchhoff’s law, the current flowing towards a junction is equal to the resistance across the junction

(c) According to Kirchhoff’s law, the current flowing towards a junction is equal to the current leaving the junction

(d) According to Kirchhoff’s law, the current flowing towards a junction is equal to all the currents in the circuit

I got this question in a job interview.

This interesting question is from Kirchoff’s Law in chapter Current Electricity of Physics – Class 12

The correct answer is (c) According to Kirchhoff’s law, the current flowing towards a junction is equal to the current leaving the junction

The explanation: According to Kirchhoff’s first law, the current flowing towards the junction is equal to the current leaving the junction. Mathematically, this law can be expressed as ∑^nK – 1 IK = 0 (where n is the number of branches carrying current towards or away from the junction)
