Chapter-3|Current Electricity| NCERT 12th Physics:

Kirchhoff’s Rule:

Kirchhoff’s First Rule:

The algebric sum of the currents meeting at a point in an electric circuit is always zero. Or

The sum of current entering the junction is equal to the sum of current leaving the junction.


Kirchhoff’s Second Rule(Loop Rule, Voltage Law):

“The algebraic sum of change in potential around a closed loop is zero.”
