I am working with a low voltage lighting system on a model train layout. Output of power source is 14volts (amps unknown). 22gauge copper/silver wire to carry load. Wiring completed in parallel with copper side to carry all positive leads and silver to carry all ground leads. Lighting is a mix of...

An ongoing debate: two 12V lead acid batteries connected in parallel - some propose some sort of see-saw current self discharge of the pair; I see no theoretic or empiric reason this should or does occur.

I work on an IT/network team. We are wanting to make sure that our switching/router hardware is properly grounded in our com room racks. Cisco is our primary vendor who recommends that you should never rely on the electrical circuit to provide adequate grounding. Instead they recommend a...

I am building a 12 micro motor wind generator array. Each motor is rated 0.2 amps at 12 volts. Each produces 12 v dc after connecting them to a rectifier, and they are all connected in parallel. How many amps will they produce altogether?

I need to build an electrical transformer for stepping up/stepping down voltages and currents. One method would be to place the secondary coil INSIDE the primary coil, as in a typical Tesla coil setup. The other method is to put the two coils SIDE BY SIDE in proximity, as is normally done. My...
