What is a leaking capacitor?
A leaking capacitor is a capacitor that loses its internal contents, such as electrolyte fluid or oil, due to damage or deterioration. This leakage often occurs in electrolytic capacitors, which are typically filled with a liquid electrolyte. Over time, this fluid can leak out due to factors such as heat, aging, or electrical stress.
