ampere-hour (Ah)

Ampere-hour (Ah) is the quantity of electrical energy equal to the flow of one ampere of current over time. Typically used to quantify battery bank capacity. The ampere-hour is frequently used in measurements of electrochemical systems such as electroplating and incorrectly, the ‘capacity’ of electrical batteries (a battery constituent material’s specific capacity is commonly expressed […]

An ampere is the unit for the electric current; the flow of electrons. One amp is 1 coulomb passing in one second. One amp is produced by an electric force of 1 volt acting across a resistance of 1 ohm. Sometimes this is abbreviated as I for intensity. The ampere is equivalent to one coulomb […]

Amorphous silicon is a non-crystalline semiconductor material that has no long-range order, often used in thin film photovoltaic modules. Used as semiconductor material for a-Si solar cells, or thin-film silicon solar cells, it is deposited in thin films onto a variety of flexible substrates, such as glass, metal and plastic. Amorphous silicon cells generally feature […]

Altitude is the angle between the horizon (a horizontal plane) and the sun’s position in the sky, measured in degrees.   Altitude or height (sometimes known as depth) is defined based on the context in which it is used (aviation, geometry, geographical survey, sport, and many more). As a general definition, altitude is a distance […]

Alternating Current AC Electric current in which the direction of flow is reversed at frequent intervals, usually 100 or 120 times per second (50 or 60 cycles per second or 50//60 Hz).   Alternating current AC From Wikipedia, the free encyclopedia “Effective power” redirects here.

Absorbed glass mat (AGM) is a fibrous silica glass mat to suspend the electrolyte in batteries. This mat provides pockets that assist in the recombination gasses generated during charging back into water.   VRLA battery From Wikipedia, the free encyclopedia 12 Volt VRLA Battery A VRLA battery (valve-regulated lead-acid battery), more commonly known as a sealed […]
