Definition

A unit of electric current that is equal to one millionth of an ampere.

Example

The circuit requires a current of 5 microamperes to function properly.

Conversation

Have you ever measured current in microamperes?

No, I usually just stick to amperes, but it sounds interesting.

Yeah, it's useful for tiny circuits where you need precision, like in sensors.

That makes sense! I should learn more about microamperes for my projects.

Root Explanation

Microampere → It is formed from "micro-" (from Greek "mikros", meaning small) and "ampere" (named after André-Marie Ampère, a French physicist, meaning a unit of electric current). The word "microampere" refers to a small unit of electric current, specifically one-millionth of an ampere.

Memory Tip

Think of 'micro-' meaning small, and 'ampere' as a unit of electric current. This helps you remember that a microampere is a very small amount of electric current.
