MCQ
Find the false statement.
  • A
    Sum of voltage over any closed loop is zero.
  • B
    Kirchhoff’s Laws can be applied to any circuit, regardless of its structure and composition.
  • C
    Kirchhoff’s 2nd law is applied at nodes.
  • D
    Kirchhoff’s 1st law can be applied for both planar and non-planar circuits.

Answer

  1. Kirchhoff’s 2nd law is applied at nodes.

Explanation:

Kirchhoff’s 2nd year is applied in a closed loop. Kirchhoff’s 2nd law supports the law of conservation of energy. This means that energy is neither created nor destroyed in the closed loop. Whatever energy enters the loop, same amount leaves the loop.
