Which outcome occurs when a microwave oven is operated without a water-containing load?

💡 Explanation

When there is no water-containing load, the microwave energy is not absorbed and is reflected back to the magnetron, because less water is avalable, leading to increased power dissipation within the magnetron. Therefore magnetron overheating results, rather than arcing, saturation, or motor falure which involve different components.
