Kirchhoff's Rules

किर्चहॉफ के नियम

Kirchhoff’s Rules is a Class 12 Physics topic in Chapter 3: Current Electricity. Students learn how the junction rule, based on conservation of charge, and the loop rule, based on conservation of energy, help analyse circuits with multiple branches, cells and resistors. The topic explains how to assign current directions and voltage signs, form simultaneous equations, and calculate unknown currents, potential differences and resistances in complex electrical networks.
