How bout plumbing used to splain lectricity ? Water pressure=volts, Gallons per minute=amps, smaller pipe size=resistance, check valves=diodes, water pumps=alternators, water turbine's=electric motors, pressure accumulators=condensers, flow restrictors=resistors, valves=switches, diverter valves=two & three way switches, water pressure reducers=transformers, storage tanks=batteries.......all about control ?
Uncontrolled electricity=lightening, uncontrolled water=flooding............Bruce
