SSC CPO 2022 PYQ — Question 81

SSC CPO - 10 Nov 2022 - Shift 2 • General Awareness • Q81

Whose law states that at a junction in an electric circuit, the sum of the currents flowing into the junction is equal to the sum of the currents flowing out of the junction?

Show answer & explanation

Correct answer: D

Explanation

The correct answer is option 4 i.e. Gustav Robert Kirchhof.

Kirchhoff's circuit laws are two equalities that deal with current and potential difference (also known as voltage) in the lumped element model of electrical circuits.

Gustav Kirchhoff, a German scientist, originally characterised them in 1845.

They are sometimes known as Kirchhoff's rules or simply Kirchhoff's laws.

These rules are applicable in both the time and frequency domains and serve as the foundation for network analysis.

Kirchhoff's first law, commonly known as Kirchhoff's junction rule, asserts that the sum of currents coming into a node in an electrical circuit equals the sum of currents going out.
