Question

On which conservation principle is Kirchhoff’s second law of electrical network is based?

Answer 1

There are basically two Kirchhoff’s Laws, these laws play a very crucial role in electronics. They are said to be the building blocks of electronics. These laws help us to find the current in a given circuit as well as we can use them to find the unknown resistance and voltage in a circuit. The laws are use in real life applications from turning on a fan to charging of a smartphone

Complete step-by-step answer:
Kirchhoff’s second law states that the sum of all voltages around a closed loop in any circuit must be equal to zero. This law is also known as Kirchhoff’s voltage law (KVL). All of us have used this law during our high school studies.

Mathematical expression can be given as
${{V}_{1}}+{{V}_{2}}=0$
The most basic use of this law is to find unknown voltage or current or resistance in a given circuit. This is the mostly used law in electronics. The whole network theory is based on this law in electronics. This law is based on the conservation of energy as voltage is a form of a potential and potential is a form of energy so, basically this law defines law of conservation of energy. So according to the question, Kirchhoff’s second law of electrical network is based on law of conservation of energy.

Note: The Kirchhoff’s first law states that the algebraic sum of current flowing through a junction is always zero, this law is also known as Kirchhoff’s Current Law as this law deals about the current. The other form of this law, we can say that at any node the incoming current is always equal to outgoing current for a particular instant of time.
