AmmoniaA compound of nitrogen and hydrogen with the formula NH3. It is normally encountered as a gas with a characteristic pungent odour but can be included in a water based form into cleaning compounds for example. |
AmperageStrength of an electrical current in amperes. |
Ampere (Amp)Electrical unit for measuring the flow of electricity in a circuit. |
Ampere-hour-rateDischarge rate used to describe what a battery will produce. For example, a 40Ah battery will produce 2A for 20Hrs. The 20hrs is an agreed value used to allow comparisons to be made. |
AmplificationAn increased electrical voltage and/or current compared to say the original signal. |
AmplifierAn electronic device that increases or allows an increased electrical voltage and/or current to flow. |
AmplitudeThe maximum distance moved by a point on a vibrating body or wave measured from its equilibrium position. It is equal to one-half the length of the vibration path i.e. half the peak to peak value of a wave. |
AmpsShort for Ampere (unit of electrical current) |
AnaerobicUsed to describe a sealant that dries when air or oxygen is excluded. |
AnalogA measuring process that uses a variable electrical current to provide a signal for computers and instruments. |
