Low-level current is most commonly measured in milliamperes. This unit is a subunit of amperes, where 1 milliampere equals one-thousandth of an ampere. The use of milliamperes is particularly relevant in the context of low-level electrical currents, such as those found in electronic devices, medical equipment, and certain beauty treatments where precision is crucial and the currents are typically much smaller than those measured in full amperes.

While volts measure the potential difference in an electrical circuit and coulombs quantify electric charge, the focus on current—the flow of electric charge—is what makes milliamperes the appropriate unit for low-level current. Ampere-hours, on the other hand, measure the amount of electric charge transferred over time rather than the immediate current flowing at a given moment, so it is not suitable for measuring low-level current directly.
