Definition of Terms - Electrical AMPERE - A unit of measure for the flow of current in a circuit. One ampere is the amount of current flow provided when one volt of electrical pressure is applied against one ohm of resistance. The ampere is used to measure electricity much as gallons per minute is used to measure water flow. AMPERE-HOUR - A unit of measure for battery capacity.

- Definition of amps, volts, watts, resistance, current, ohms, electrical phases. We include basic formulas relating amps, volts, resistance, watts, and we explain what these electrical terms mean in practical applications such as for building or appliance electrical power, electrical wiring, and basic troubleshooting. ten-amp 240V electrical service is capable of delivering, speaking roughly, twice the energy to the end-user than a ten-amp 120V electrical service. So volts is a measure of the strength of an electrical source at a given current or amperage level.

Home Appliance Amp Reference Chart First, you need to know how many amperes, or amps, for which a circuit is rated. An amp is the amount of electrical current that flows through a circuit. In most homes, lighting and small appliance circuits are 15 or 20 amps, and major appliances are on 20, 50 or even 60 amp circuits.Second, you need to know the volts flowing through the wires.enerally, household wiring is 120 or 240 volts. To determine the amount of wattage a branch circuit can handle, multiply the circuit's amperage by the circuit's volts. A 20-amp, 120-volt circuit can handle 2,400 watts.

amperage Abbreviation: amp. The amperage, on the other hand, is that of the six cells combined, or 150. Voltage, amperage, and watt or kilowatt are the terms in common use. Then he defines the wave-form, voltage, and amperage entering the circuit and defines whatever is coming out. The name plates on electric motors indicate the amperage at full load. Then the voltage is lowered to a suitable rate, and the amperage raised in proportion, by special machinery, at the point of use.

QUICK TIP â Whatâs the difference between Amps, Volts and Watts? The water pressure would be the voltage. Watts would be the power (volts x amps) the water could provide (think back to the old days when water was used to power mills). So with this analogy in mind the definitions below for amp, volt and watt should be easier to understand: Amp – an ampere is the unit for measuring electricity.

ampere hour (Ah or amp hour) An ampere hour (abbreviated Ah, or sometimes amp hour) is the amount of energy charge in a battery that will allow one ampere of current to flow for one hour. An ampere is a unit of measure of the rate of electron flow or current in an electrical conductor. One ampere of current represents one coulomb of electrical charge moving past a specific point in one second. A milliampere hour (mAh) is 1,000th of an Ah, and is commonly used as a measure of charge in notebook computer batteries. The mAh provides an indication of how long the PC will operate on its battery without having to recharge it.

What is Amperage? Amperage is a term often used by electricians, and means electrical current, measured in amperes, or amps. The ampere is the SI unit for electrical current, or the amount of electrical charge that flows through a conductor in a given time.One ampere is a charge of one coulomb — about 6.241 X 10 18 electrons — per second flowing past a given point. current of one amp at one volt uses one watt of power. The power used by a device is simply amps multiplied by volts, so an appliance rated at ten amps plugged in to a 110-volt supply will use 1,110 watts.

CoStar Glossary Amperage is a measure of the electrical current flowing through a circuit. Current is measured in amperes or amps. You must use the correct size wire for the amperage requirement of the circuit to prevent the wire from over heating. The number and type of electrical devices connected to a circuit determine the amperage requirement of the circuit.

Amplifier In this example the amplifier has a voltage gain of 3; that is at any instant v o = 3 v i {\displaystyle v_{o}=3v_{i}\,}. An amplifier, electronic amplifier or (informally) amp is an electronic device that can increase the power of a signal (a time-varying voltage or current). An amplifier uses electric power from a power supply to increase the amplitude of a signal.
