A capacitor is a device that stores and releases electrical charge. Capacitors are necessary for the operation of most electronic devices, like computers or cell phones. The function of capacitors on a motherboard is to store power when the computer starts up and release it when needed. Without capacitors, these electronics would not work properly because there would be no stored power available to meet their demands.
A capacitor is an electronic component mainly used to store electric charge. Capacitors are made up of two metal plates with a layer of insulation in between, which creates a separation that stores the electricity. The function of capacitors on a motherboard is to filter any noise or unwanted signals from entering your computer system, protecting it against interference and creating smooth power flow.
The capacitors on the motherboard are used to store electric charge. They filter out any excess voltage spikes that can damage components of the computer. This is one of many ways they help prevent short circuits and other electrical problems. Read more about how capacitors protect your PC here!
