Explain Kirchoff's laws with examples.

 Answer:

1. Junction Law: At any junction point in a circuit, the sum of the currents into the junction must equal to the sum of the currents leaving the junction.

From the figure, we have

   I₁ + I₄ + I₆ = I₅ + I₂ + I₃

This law is based on the law of conservation of energy.

2. Loop Law: The algebraic sum of increases and decreases in potential difference across various components of the circuit in a closed loop must be zero.

This law is based on the conservation of energy.

Let us apply the Loop law in the above circuit diagram,

   We know that from Ohm's law, V = IR

   For the loop ACDBA, -V₂ + I₂R₂ -I₁R₁ +V₁ = 0

   For the loop EFDCE, -(I₁ + I₂)R₃ -I₂R₂ +V₂ = 0

   For the loop EFBAE, -(I₁ + I₂)R₃ -I₁R₁ +V₁ = 0
