In lesson 48, we examined how power came into your house or plant. It is sent to you in AC form, because it is less expensive, as well as more stable, to send it in a high voltage, low current form, and transform it to lower voltages at higher currents...

Recall that in a semiconductor diode, we have 2 regions of DOPED semiconductive material. One region is doped positive, and the other region is doped negative. There is also a junction, where the two regions are joined.When a diode is forward biased...

But we've already discussed diodes. They are a simple form of vacuum tube aren't they?Well - yes and no.While diodes existed in tube form for many years vacuum tube diodes had their problems, and the electronics industry would try to find a way around...
