Automotive Capacitor

This article discusses the factors affecting the capacity of a capacitor, the unit of capacitor, and the operation of a capacitor in an ignition circuit.

Questions

• What are the factors affecting the capacity of a capacitor?
• What is the unit of capacitor?
• How does a capacitor work in an ignition circuit?

Answers

• The factors affecting the capacity of a capacitor are the area of the plates holding the charges, the number of plates used, the distance the plates are separated, and the type of dielectric.
• The unit of capacitor is the farad. However, automotive capacitors are generally measured by micro farad.
• A capacitor in an ignition circuit stores energy and then releases it to create a spark at the spark plug.
