What Does a Capacitor Do In Electrical Work?
A capacitor is an electrical component used in many types of electronic and electrical applications, including both AC and DC circuits. A capacitor’s purpose is to store energy in an electrical field in much the same way a battery stores energy as chemical energy. This stored energy can then be released back into the circuit to regulate current, reduce voltage peaks, or provide a short burst of additional energy when needed.
Capacitor Usage In Electrical Work
Capacitors are used in a variety of electrical applications, including:
- Filter capacitors: primarily used in AC circuits to reduce voltage spikes and other noise disturbances.
- Voltage regulators: used to ensure a steady AC output voltage.
- Electronic timing devices: used with resistors to create time delays for some digital and logic circuits.
- Voltage multipliers: used to boost or increase AC voltages.
- Motor starters: used to help motors to start more safely, and to reduce the strain placed upon the motor.
Having a good understanding of capacitor usage in electrical applications is key to proper electrical system design. Capacitors can be used in a variety of ways to regulate current, reduce voltage peaks, and provide short bursts of energy when needed. By selecting the right capacitors for the application, an electrical system can be more reliable and efficient.
