← ScienceWhich outcome occurs when a resonant cavity magnetron accumulates internal charge?
A)Decreased output power✓
B)Adjusted operating frequency
C)Harmonic frequency generation
D)Increased electron transit time
💡 Explanation
Decreased output power occurs; space charge imbalances disrupt the electron dynamics. This is because the resulting electric field impedes the efficient extraction of microwave energy via *space charge limitation*; therefore power drops, rather than changes in cavity resonance properties.
