What is 1/1,000 of an ampere called?

Explanation:
In the SI system, milli- is a prefix meaning one thousandth. The ampere is the base unit for electric current, so 1/1000 of an ampere is one milliampere, abbreviated mA. This unit is commonly used for small currents in electronics, such as sensors, LEDs, and small devices. Remember the relationship: 1 A = 1000 mA, and 1 mA = 0.001 A. The other terms shown are not current units: an ampere is the base unit for current, a volt measures electric potential, and an ohm measures resistance. So the correct choice is milliampere.
