| Monophasic phase | Single phase, phase duration is synonymous with pulse duration |
| Cation | Positively charged ion |
| Hertz | Unit of frequency or cycles per second for alternating current |
| Frequency | Number of cycles per second that a wave form exhibits |
| Volt | Unit of electromotive force |
| Watt | Electrical unit for power |
| Ampere | Unit of current, indicates the rate of electron flow |
| Ion | An atom no longer in its original neutral state, but electrically charged |
| Anion | Negatively charged ion |
| Molecule | Chemical combination of two or more atoms |
| Electric field | Space around a charged particle in which the charge has an effect |
| Electric current | Flow of electrons from a negative pole to a positive pole through a conduction medium |
| Ohm | Defines the amount of resistance offered by a conducting medium |
| Direct current | One-way flow of electrons for about one second or larger |
| Biphasic phase | Phase duration is determined by adding the total time of the two phases within each pulse |
| Polyphasic phase | Phase duration is determined by summing the durations of all the phases in a single pulse |
| Atom | smallest particle of an element that can take part in a chemical reaction |
| Proton | Positively charged particle forming the nucleus of an atom |
| Electron | Negatively charged particle of an atom |
| Electromotive force | Electric postential difference or voltage |
| Amplitude | Highest point of a wave or from peak to valley if it crosses the isoelectric line |
| Direct current | One-way flow of electrons for one second or longer |
| Alternating current | Current that flows in one direction and then reverses its direction of flow at least once every second |
| Phase | Moment the current leaves the isoelectric line, or zero baseline, to the moment the current returns to the baseline |
