Question

Assertion (A): A network in which circuit elements like resistance, inductance and capacitance cannot be physically separated or analysis purpose is called lumped network. Reason (R): Most of the electric network are lumped in nature.

• A. Both (A) and (R) are correct and (R) is correct explanation
• B. Both (A) and (R) are correct but (R) is not explanation
• C. (A) is correct but (R) is incorrect
• D. (A) is incorrect but (R) is correct

Hint:

Lumped → separable elements; Distributed → continuous parameters.

Answer 1

The Correct Option is D

Concept:
• Lumped network → elements are concentrated and separable
• Distributed network → parameters are spread continuously

Step 1: Analyze Assertion Assertion states elements cannot be separated → this is definition of distributed system. \[ \Rightarrow \text{Assertion is FALSE} \]

Step 2: Analyze Reason Most practical low-frequency networks are lumped. \[ \Rightarrow \text{Reason is TRUE} \] \[ \therefore \text{Correct answer is (D)} \]
