Current Source ConceptHardQuestion 31683

Question

An ideal current source has:
  1. A
    Zero internal resistance
  2. B
    Infinite internal resistance
    Correct
  3. C
    Zero output voltage
  4. D
    Fixed terminal voltage

Correct answer

Infinite internal resistance

Explanation

An ideal current source delivers constant current regardless of load. This requires infinite internal resistance (so load doesn't affect current). Contrast: ideal voltage source has zero internal resistance.
