Question

Internal resistance of an ideal voltage source is:

• A. 0
• B. 1K
• C. 2K
• D. \(\infty\)

Hint:

An ideal voltage source delivers constant voltage with zero internal resistance. Ideal current source has infinite internal resistance.

Answer 1

The Correct Option is A

An ideal voltage source is defined to have zero internal resistance. This ensures the voltage remains constant regardless of the current drawn.
Real voltage sources have some internal resistance.
