What is the unit of electric current?

Explanation:
Electric current is the rate at which electric charges flow through a conductor. The unit that measures this rate is the ampere, often shortened to amp. By definition, one ampere means one coulomb of charge passing a given point every second. The ampere is the standard SI unit for measuring current and is named after André-Marie Ampère. In circuits you’ll encounter an ammeter used to measure this current. The other units in the list measure different quantities: volt is electric potential difference (how much push drives the charges), watt is electrical power (how much energy is used or produced per unit time), and hertz is frequency (how many cycles per second). For very small currents, we use smaller units like milliamperes or microamperes.
