Capacitor
A capacitor is an important electrical part found in many household and industrial appliances. It's like a small battery that temporarily stores and releases electrical energy. Maintenance technicians often need to check, test, and replace capacitors in devices like air conditioners, washing machines, and power tools. When a capacitor fails, it can cause appliances to work poorly or stop working altogether. This component is sometimes also called a "condenser" in older documentation or job listings.
