Why are heavy-gauge wires used for a 100-watt transceiver's DC power connection?
- A To minimize the voltage drop
- B To prevent an electrical shock
- C To avoid RF interference
- D To minimize ripple
Correct answer: A — To minimize the voltage drop. From the official ISED question bank, verified word for word.
Why
Heavy-gauge wires have a thicker metal core, which lowers electrical resistance and allows more current to flow with less energy lost as heat. The full explanation — and one for every question — is in Pro.
