Hi all, first incredible site, I am learning so much here (teaching myself electronics and all about circuits is better than any book I have tried!)
The way I am learning about current flow/electron flow is that it flows from the negative side of the power source to the positive (electron flow theory).
Last night on a bread board, I wired up a 9v battery a resistor, and an LED.
The (-) ground of the battery went to the resistor, which went to the cathode (flat side) of the LED and then the anode went on to the (+) terminal of the 9v battery. But I got nothing. Until I flipped the positive and negative wires on the battery then the LED lit up.
Wired this way, it means current is flowing from the + terminal of the battery to the cathode of the led, instead of the other way, right?
This sounds like the battery is labeled using "conventional flow" instead of "electron flow". Is this the case and is it like that for all batteries? Or do I need to go back to square one because I have it all wrong in my head
Thanks!!
