Question
The power delivered by the current source, in the figure, is ________.
Correct answer
3 to 3
Solution
Take the bottom wire as ground. Label the nodes on the 1 Ω–1 Ω row as L (left), M (middle, above the 2 A source) and R (right).Node voltages fixed by the sources.
- The left 1 V source (positive at the top) connects ground to L: V.
- The top 1 V source sits between L and R with its positive terminal on the L side: V. (So the right-hand 1 Ω to ground carries no current.)
