Which term describes the strength or intensity, expressed in volts or milliamps?

Explanation:
The strength or intensity of an electrical stimulus is described by the stimulus amplitude. This is the amount of voltage or current delivered with each pulse, and it’s expressed in volts for voltage-driven devices or milliamps for current-driven devices. Adjusting the amplitude changes how strongly nerves are recruited and how intense the sensation feels, within safety limits. Other parameters define timing rather than strength: duration refers to how long each pulse lasts, frequency is how often pulses occur per second, and duty cycle is the proportion of time the current is on during a cycle.
