GATE 2016 EE (EE2) – Question 33

The voltage and current sources in the circuit are ideal. The output voltage across the current source, in volts, is

Show answer and explanation

Correct answer: (D) 20

Explanation

The 5 A source injects current into the upper output node. That current must flow leftward through the 2 Ω resistor to the 10 V source.

The output node is consequently 5×2=10 V above the voltage source's upper terminal. Thus Vout=10+10=**20 V, D**, with the marked positive polarity.
