Which risk increases when a series capacitor is undersized within a resonant circuit?

A)Circuit overcurrent and component failure
B)Increased electromagnetic interference emissions
C)Subharmonic oscillations in switching regulators
D)Transformer core saturation and overheating

💡 Explanation

Circuit overcurrent and eventual component failure risk rises because `impedance matching` degrades with an undersized capacitor; therefore larger circulating currents occur triggering overcurrent protection, or component breakdown, rather than resonance at the intended frequency.
