Overview

• Kirchhoff’s Current Law (KCL):

  This law states that the total current entering a junction (or node) in an electrical circuit is equal to the total current leaving the junction. This follows the principle of conservation of charge.

∑ I_in=∑ I_out

• Kirchhoff’s Voltage Law (KVL):

  This law states that the sum of all voltages around a closed loop in an electrical circuit is equal to zero. This follows the principle of conservation of energy.

∑ V=0

Significance

• Kirchhoff’s Current Law (KCL): Ensures current conservation at junctions, helping to analyze and distribute current in parallel circuits.

• Kirchhoff’s Voltage Law (KVL): Ensures energy conservation in closed-loop circuits

and is used to calculate unknown voltages.
