Question

alternating current flows in ___ direction(s) and direct current flows in ___ direction(s).

both/one
both/both
one/one
one/both

Explanation:

Analyze alternating current direction

Alternating current (AC) periodically reverses its direction, meaning it flows in both directions.

Analyze direct current direction

Direct current (DC) flows continuously in only a single direction, meaning it flows in one direction.

Match with options

The sentence is: "Alternating current flows in ___ direction(s) and direct current flows in ___ direction(s)."
Substituting the findings: "both" for the first blank and "one" for the second blank. This corresponds to the option "both/one".

Answer:

• (A) both/one (Correct answer)
• (B) both/both
• (C) one/one
• (D) one/both
