Units of Current

Once the unit of charge is understood, most other units used in electronics become simple. 

REMEMBER:  In the field of electronics, we use the coulomb exclusively!

Electrical current is measured in amperes.  An ampere is reached when one coulomb of charge is conducted in one second.

The ampere is named after André-Marie Ampère and is often shortened to just amp.

The ampere's symbol is "A"

In the common water analogy, current is like the current in a river measured in gallons per second.

The ampere is that constant current which, if maintained in two straight parallel conductors of infinite length, of negligible circular cross-section, and placed 1 meter apart in vacuum, would produce between these conductors a force equal to 2 × 10−7 newtons per meter of length.
