MCQ
The equation $\rightarrow ∑e = ∑IR$ is applicable to which law?
  • Kirchhoff’s second law.
  • B
    Kirchhoff’s junction rule.
  • C
    Kirchhoff’s third law.
  • D
    Newton’s Law.

Answer

Correct option: A.
Kirchhoff’s second law.

The equation $\rightarrow ∑e = ∑IR$ is applicable to Kirchhoff’s second law. This law is also known as Kirchhoff’s loop rule. This expression tells us that in a closed loop, the algebraic sum of the emfs is equal to the algebraic sum of the products of the resistance and currents flowing through them.
