T5A11
What type of current flow is opposed by resistance?
- A.Direct current
- B.Alternating current
- C.RF current
- D.All these choices are correct (correct answer)
WhyDirect current, alternating current, and RF current are all opposed by resistance. Resistance opposes the flow of any current, whether it's steady DC, alternating current, or current at radio frequencies, so all three choices are correct, answer D. Singling out just DC (A), AC (B), or RF (C) would incorrectly suggest resistance only affects one type of current flow.
