A current that flows while no power is dissipated is sometimes called a:
AWattless current
BWattage current
CWasteful current
DWatchful current
Answer & Solution
Correct answer: A. Wattless current
1. In a purely reactive circuit the power factor is zero.
2. Current still flows, but no energy is consumed.
3. This current is sometimes referred to as wattless current.
4. So the answer is wattless current.
