Question.4
A product has been in use continuously for 3+ years in a warm environment.
On inspection, the electrolytic capacitors appear physically normal, but the circuit now shows more noise and occasional instability.
What is the most likely capacitor-related cause?
Select Answer
Capacitance has increased due to charge buildup
Dielectric has improved with temperature cycling
Internal ESR has increased, reducing filtering performance
The capacitor has become non-polarized due to aging
