In the figure shown below. Find the voltage across 2Ω resistor due to all source using Superposition theorem.

(a) 3.41

(b) -3.41

(c) 3.14

(d) -3.14

This question was posed to me during an interview.

This intriguing question comes from Superposition Theorem in chapter Useful Theorems in Circuit Analysis of Network Theory

Best answer
Right answer is (b) -3.41

For explanation: The algebraic sum of all the voltages obtained by considering individual sources is the voltage across 2Ω resistor. V = 0.97-2.92-1.46 = -3.41V.
