2. Waveguide
- Channels microwave energy from the magnetron into the cooking cavity.
- Often made of metal, designed to prevent leakage.
3. High-Voltage Transformer and Rectifier
- Supply and convert electrical power to the magnetron.
- The transformer steps up voltage; rectifier converts AC to DC.
4. Capacitor
- Stores electrical energy to supply the magnetron.
