Question

Explain Kirchoff's First and Second Law of Current.​

Answer 1

Kirchhoff's voltage law (2nd Law) states that in any complete loop within a circuit, the sum of all voltages across components which supply electrical energy (such as cells or generators) must equal the sum of all voltages across the other components in the same loop.

Answer 2

Kirchoff's First and Second Law of Current.

1. Kirchhoff's First law:

Kirchhoff's First law States that at the junction of electrical circuit, the amount of current flowing in is equal to the  amount of current flowing out of the junction.

• It is also called as a junction rule or Kirchhoff's current rule.
• This law is based on conservation of electric charges.

2. Kirchhoff's second law:

Kirchhoff's second law states that the algebraic sum of all the potential difference along a closed loop in a circuit is zero.

• This law is also known as loop or voltage law and based on law of conservation of energy.
•  For  using this law, we have to start from a point on the loop either clockwise or anticlockwise throughout the loop to come to the same point on the loop.
