Re: [wsjtgroup] Stupid electronics questions
- The black line is the cathode. That is connected to the positive side if
you want the diode off like across a relay. The cathode is connected to the
negative voltage if you want the diode on like in a logic circuit.
This diode symbol ->|-, the bar | is the cathode and the anode is the arrow >.
Quoting Jacob Tennant <k8jwt@...>:
> 1. On a diode (1N4148) the little black line goes closest to the negative
> the positive?
> 2. On a 12volt reed relay, the power & ground goes to the coil contacts?
