Question

When one applies Kirchhoff loop rule, the algebraic sum of the potential drops across the cells and resistors is zero. Why? Write practical applications of this Law..​

Answer 1

Answer:

Kirchhoff's loop rule states that the algebraic sum of the voltage differences is equal to zero. ... The potential drop, or change in the electric potential, is equal to the current through the resistor times the resistance of the resistor.

Answer 2

The correct answer to the above question is -

• When one applies the Kirchhoff loop rule, the algebraic sum of potential drops across the cells and resistors is zero. This is because of Law of conservation of mass and the law of conservation of energy.
• The potential drop or, change in electric potential is equal to the current flowing through the resistor and the equivalent resistance of the resistor

Application of Kirchhoff's law -

• Kirchhoff loop law is used to find the value of current, potential difference, and internal resistance in the DC circuit.
• Wheatstone bridge is the major application of Kirchhoff's law.
• It is also used in mesh and node analysis.
