Common Questions
What does an ampere measure?
An ampere measures electric current, the rate at which electric charge flows. One ampere corresponds to one coulomb of charge passing per second.
Can amperes be converted directly to watts?
Not without voltage and the applicable circuit conditions. In a simple DC circuit, watts equal volts multiplied by amperes.
Are amps and amp-hours the same?
No. Amps measure current at a moment in time. Amp-hours measure electric charge capacity accumulated over time.
Does a current value alone determine electrical danger?
No. Risk also depends on voltage, current path, duration, frequency, source capability, environment, and other conditions. Do not use a unit converter as electrical safety guidance.
