Diodes are semiconductor components made from a P-type (or metal in Schottky diodes) and N-type material (usually silicon, but germanium, selenium, and gallium arsenide can also be used), that allow current to flow in one direction only.

Braking with an electric motor
In some H-bridge drives you sometimes see modes where both low-side drives (with both high side drives OFF!) are turned on simultaneously to provide braking. This lets current generated in the motor l …

30 amp 12 v diode
You could do it with diodes, but high current in a diode like that will generate a lot of heat. … This way your diodes only need to be rated for a few hundred mils at most. …

Circuit with V AC and V DC after rectification
If you're feeding regular AC through a full-wave rectifier (the four diodes you mention), the resulting waveform may well give you funny readings on ordinary DVMs. …

Is paralleling diodes a bad idea?
you put a low value resistor, for example 1 ohm or 1/2 ohm, something like that, in series with each diode, and then parallel those assemblies, the resistors help to keep the load even between the two diodes …

Electronic circuit switch for arduino
It's hard to tell from that picture, but it looks like you have maybe two wires from the arduino going to the breadboard, and two wires going from the breadboard to that thing on the left. Assuming th …
