what does ampere measure

Ampere measures electric current — the rate at which electric charge flows through a conductor.

Quick answer

• 1 ampere = 1 coulomb of charge per second.

• It’s usually measured with an ammeter or a multimeter set to current mode.

In plain English

If voltage is the “push,” amperes tell you how much electricity is flowing. That’s why amps matter for things like circuit safety, appliance ratings, and battery performance.

Example

A device drawing more amps is pulling more current from the circuit, which can mean more power use or a greater need for proper wiring and protection.

If you want, I can also explain amps vs volts vs watts in one minute.
