A sample from this course

One topic, as StudyPath teaches it.

Passage of electricity in gases and in evacuated tubes and applications

This topic explains how electric current can pass through gases and through evacuated tubes, even though gases are normally poor conductors. For exam success, you must understand ionization, discharge conditions, cathode rays, thermionic emission, and the practical uses of gas-discharge and vacuum-tube devices.
