What does peak current refer to?

Peak current refers to the maximum current flow in a given waveform. In electrical contexts, this is particularly relevant in alternating current (AC) systems, where the waveform is not constant but fluctuates over time. The peak current is crucial because it indicates the highest level of current that can occur, which can impact circuit design, safety, and device performance.

Understanding peak current is essential for determining how much current a system can handle without overheating or causing damage. This concept is significant in applications involving electrical stimulation, where devices need to deliver specific peak currents to achieve desired therapeutic effects without risk of harm.
