← ScienceWhich risk increases when a spacecraft's power capacitor bank overheats?
A)Decreased capacitance energy storage✓
B)Increased magnetic field generation
C)Enhanced radio-frequency signal fidelity
D)Improved radiation shielding effectiveness
💡 Explanation
Decreased capacitance occurs because elevated temperatures increase the dielectric material's ion mobility inside the capacitor, initiating dielectric breakdown, which drops capacitance, and potentially causes catastrophic system failure, rather than alternative effects related to magnetics.
