Internal resistance of an ideal current source is:
Correct answer: A. Infinite
- A. Infinite
- B. Very low
- C. Zero
- D. Very high
Explanation
An ideal current source is a theoretical device that delivers a constant current regardless of the voltage across it. To achieve this, it must have an infinite internal resistance in parallel with the source, preventing any current from being diverted internally.

About Current Electricity
Steady current relates charge flow to potential difference, resistance and resistivity, including how temperature changes a conductor's resistance. Sources with internal resistance have terminal voltage below their emf when delivering current, and maximum power output occurs under a specific load condition rather than at zero resistance.
