A capacitor, also called a storage cell, secondary cell or condenser, is a passive electronic component that can store an electrical charge. It is also a filter that blocks direct current (DC) and allows alternating current (AC) to pass through.
A capacitor, also called a storage cell, secondary cell or condenser, is a passive electronic component that can store an electrical charge. It is also a filter that blocks direct current (DC) and allows alternating current (AC) to pass through. Unlike some capacitors, a ceramic capacitor is not polarized, which means that the two electrodes are neither positively nor negatively charged.
