← ScienceWhich risk increases when a bypass capacitor degrades?
A)Increased inductive impedance in circuit
B)Excessive electromagnetic interference emission✓
C)Reduced dielectric breakdown voltage
D)Oxidation of adjacent passive components
💡 Explanation
Increased electromagnetic interference (EMI) occurs via weakened decoupling. The degraded capacitor’s increased impedance allows higher frequencies to propagate directly to ground, thus generating EMI; rather than filtering, because impedance rises; therefore causing emissions.
