# What is KCL and KVL law?

What is KCL and KVL law?

Kcl means sum of entering currents is equal to sum of leaving currents.

Kvl means sum of voltages around a clised loop is equal to zero.

Basically KCL and KVL are two laws that are presented by Kirchoff

KCL stands for kirchoff, s current law

And

KVL stands for kirchoff, s voltage law

According to KVL:sum of all the voltages in a closed loop is zero

For example

v1 +v2+ v3+ v4 =0

According to KCL:

Incoming current=outgoing current

Description : State and explain Lenz's law.

Last Answer : Lenz’s law: It states that the direction of statically induced emf is such that it always opposes the cause that produces it. In fact, the induced emf produces current, which produces magnetic flux and this magnetic flux opposes the changing magnetic field that is responsible for emf induction.

Description : State Faraday's law of electromagnetic induction.

Last Answer : First Law: - Whenever change in the magnetic flux linked with a coil or conductor, an EMF is induced in it. OR Whenever a conductor cuts magnetic flux, an EMF is induced in conductor.  Second Law: ... of induced EMF is directly proportional to (equal to) the rate of change of flux linkages.
