A half-wave dipole antenna is normally fed at the point where:
- Athe voltage is maximum
- Bthe resistance is maximum
- Cthe antenna is resonant
- Dthe current is maximum
Correct answer: D — the current is maximum. From the official ISED question bank, verified word for word.
Why
A half-wave dipole is fed at its centre, where the electrical current flowing through the antenna reaches its highest point while the voltage is at its lowest. The full explanation — and one for every question — is in Pro.
