Under normal operating condition voltage clamping device offers impedance of_________?
Correct answer: A. high value.
- A. high value.
- B. low value.
- C. zero value.
- D. moderate value.
Explanation
A voltage-clamping device must draw negligible current during normal voltage, so it presents high impedance. When a surge occurs, its impedance falls and it diverts or limits the excess voltage.
