Internal resistance of ideal voltage source is ?
Correct answer: A. zero
- A. zero
- B. infinite
- C. finite
- D. 100 ohms
Explanation
An ideal voltage source maintains constant terminal voltage regardless of load current, which requires zero internal resistance. Any nonzero resistance would cause a voltage drop when current flows.
