In a half-wave dipole, the lowest distribution of _________ occurs at the middle.
- A capacity
- B inductance
- C current
- D voltage
Correct answer: D — voltage. From the official ISED question bank, verified word for word.
Why
In a half-wave dipole, the electrical pressure called voltage is lowest at the exact centre where the antenna is fed, while the flow of electrons known as current is highest there. The full explanation — and one for every question — is in Pro.
