If the energy is supplied from a source, whose resistance is 1 ohm, to a load of 100 ohms the source will be___________?
Correct answer: A. a voltage source
- A. a voltage source
- B. a current source
- C. both of above
- D. none of the above
Explanation
Because the source resistance is much smaller than the 100-ohm load, nearly the full source voltage appears across the load and the source behaves as a voltage source. A current-source approximation requires source resistance to be much larger than the load.

The more specific you are, the faster it gets fixed. A source beats an opinion.
