Question

What is Kirchhoff's law? Explain its both law?With example​

Answer 1

${\huge {\underline {\tt {\blue {Answer}}}}}$

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

✒They were first described in 1845 by German physicist Gustav Kirchhoff.

✒This generalized the work of Georg Ohm and preceded the work of James Clerk Maxwell.

✒Widely used in electrical engineering, they are also called Kirchhoff's rules or simply Kirchhoff's laws.

✒These laws can be applied in time and frequency domains and form the basis for network analysis.

✒Both of Kirchhoff's laws can be understood as corollaries of Maxwell's equations in the low-frequency limit.

✒They are accurate for DC circuits, and for AC circuits at frequencies where the wavelengths of electromagnetic radiation are very large compared to the circuits.

Answer 2

Answer:

Kirchhoff's law :-

Kirchhoff's law :-There are two main laws that Kirchhoff invented.

Kirchhoff's junction law :-

It says that the sum of currents entering a junction must equal the sum of currents leaving the junction. This is a consequence of charge conservation.

Kirchhoff's loop law :-

says that the sum of the changes in voltage around and closed loop in a circuit must always be zero.This again is a consequence of charge conservation and also conservation of energy.
