In a half-wave dipole, where does minimum voltage occur?
- A It is equal at all points
- B Both ends
- C The centre
- D At the right end
Correct answer: C — The centre. From the official ISED question bank, verified word for word.
Why
In a half-wave dipole, the voltage is lowest right at the centre because that is where the antenna connects to the feedline and current flows most freely. The full explanation — and one for every question — is in Pro.
