What type of current flow is opposed by resistance?

  1. Direct current
  2. Alternating current
  3. RF current
  4. All these choices are correctПравильный ответ

Объяснение

Resistance opposes the flow of charge regardless of the waveform, so it acts on direct current, alternating current, and RF current alike. Reactance adds further opposition as frequency rises, but that does not exempt any of these from resistance.
