Capacitance (T&M)

The Capacitance 4 hour PDH Time & Monitored online course is a part of the Electrical category courses. This courses provide guidance on use of capacitor devices and the theory behind. Inductance is the property of a coil that causes electrical energy to be stored in a magnetic field about the coil. The energy is stored in such a way as to oppose any change in current. Capacitance is similar to inductance because it also causes a storage of energy. A capacitor is a device that stores electrical energy in anelectrostatic field. The energy is stored in such a way as to oppose any change in voltage. This course also explains how capacitance opposes a change in voltage.

This course is based on Chapter 3 of Module 2, “Capacitance” of the Navy Electricity and Electronic Training Series (NAVEDTRA 14174),.

This course is intended for use by electrical engineers, design and construction professionals, students and others interested in learning about basic electrical theory.
