The alternating current can be transmitted:
Correct answer: D. both a and c
- A. Very low cost
- B. To very high cost
- C. long distance
- D. both a and c
Explanation
The correct option, "both a and c," indicates that alternating current (AC) can be transmitted over long distances (option c) and, in some cases, at relatively low costs (option a). This acknowledges the capability of AC for efficient long-distance transmission while also considering potential cost factors.

About Alternating Current
Alternating current varies periodically, so phase relationships become essential when current passes through a resistor, capacitor or inductor. The chapter distinguishes resistance from capacitive and inductive reactance, explains phase lead and lag, and connects changing electric and magnetic fields with the production and properties of electromagnetic waves.
