Consider the circuit shown below. Find the voltage across 2Ω resistor due to the 10V voltage source using Superposition theorem. Correct Answer 1

Short circuiting 20V source, open circuiting 2A source, Voltage at node A is (V-10)/10+V/20+V/7=0 => V=3.41V. => The voltage across 2Ω resistor is V/(7)×2=0.97V≅1V.
