Question

In superposition theorem, voltage source is replaced by ________ and current source by ________.

• A. open circuit, short circuit
• B. short circuit, open circuit
• C. short circuit, short circuit
• D. open circuit, open circuit

Hint:

During superposition, short voltage sources and open current sources to analyze their separate effects.

Answer 1

The Correct Option is A

Step 1: Superposition theorem states that the contribution of each independent source is considered separately.
Step 2: To isolate sources:
Replace a voltage source with a short circuit (\( V = 0 \Rightarrow wire \))
Replace a current source with an open circuit (\( I = 0 \Rightarrow no path \))
This allows individual analysis without interference from other sources.
