Detailed explanation-1: -An ampere (AM-pir), or amp, is the international unit used for measuring current. It expresses the quantity of electrons (sometimes called “electrical charge") flowing past a point in a circuit over a given time.
Detailed explanation-2: -One ampere of current represents one coulomb of electrical charge (6.24 x 1018 charge carriers) moving past a specific point in one second. Physicists consider current to flow from relatively positive points to relatively negative points; this is called conventional current or Franklin current.
Detailed explanation-3: -Named for 19th-century French physicist André-Marie Ampère, it represents a flow of one coulomb of electricity per second. A flow of one ampere is produced in a resistance of one ohm by a potential difference of one volt.
Detailed explanation-4: -If you’re working on an electrical project, sometimes you may need to check the amperage, or how much electricity is flowing through the circuit. While this is not a common test, you might need to measure amps to determine if something is pulling more energy than it should.
