Question

Magnetron tube filament voltage in a microwave oven is ________.

• A. 3·2 V AC
• B. 3·0 V AC
• C. 2·0 V AC
• D. 1·0 V AC

Hint:

Microwave ovens depend on a magnetron, and its filament voltage is typically in the range of 3-2 V AC.

Answer 1

The Correct Option is A

The magnetron tube in a microwave oven operates at a filament voltage of 3-2 V AC. This low voltage is critical for heating the filament and generating microwaves efficiently.
