Current cannot flow to ground through _______________?
Correct answer: C. a virtual ground
- A. a mechanical ground
- B. an a.c. ground
- C. a virtual ground
- D. an ordinary ground
Explanation
A virtual ground is maintained at approximately 0 V by circuit action but has no direct physical connection to ground, so it is not a path for current to reach ground. It should not be confused with an ordinary grounded node.
