The notation to state a resistor''s value in a circuit diagram varies. One common scheme is the RKM code following IEC 60062.Rather than using a decimal separator, this notation uses a letter loosely associated with SI prefixes corresponding with the part''s resistance.For example, 8K2 as part marking code, in a circuit diagram or in a bill of materials (BOM) indicates a resistor value …

Richard Pattle was the first who remarked that the combination of river water with seawater can be used as a power source in a ''hydroelectric pile'' (Pattle, 1954, Pattle, 1955a).He stated in 1954: ''The osmotic pressure of sea-water is about 20 atmospheres, so that when a river mixes with sea, free energy equal to that obtainable from a waterfall 680 ft high is lost''.
The first lead-acid gel battery was invented by Elektrotechnische Fabrik Sonneberg in 1934. [5] The modern gel or VRLA battery was invented by Otto Jache of Sonnenschein in 1957. [6] [7] The first AGM cell was the Cyclon, patented by Gates Rubber Corporation in 1972 and now produced by EnerSys.[8]The Cyclon was a spiral wound cell with thin lead foil electrodes.
