An electric current is formed by the flow of charge carriers through a conducting material, similar to water flowing through a pipe. The base SI unit ampere (A) is defined…
The graph above depicts the relationship between current, frequency and biological effect on sensation and muscle contraction. At high frequencies, greater current flow is required to cause muscle contraction and…
Capacitors are passive components that store electrical energy. The ability of the capacitor to store charge is its capacitance and is measured in farads (F). The capacitor consists of two…
A lead wire and voltmeter attached to the electrode allows measurement of the potential relative to a reference point. The reference point is usually a second skin electrode. Signals are…
