P-Channel MOSFET as inverter

In a previous circuit, which you can find on my profile, I showed how to make an inverter with an NPN transistor. This one is simpler and more efficient in terms of inverting, however the MOSFET only lets a small voltage and current through, hence 9V are required for a single LED.

If you have a fix for that, let me know! :P

The MOSFET has some settings, width and length. Width is how wide the river is, but length is messed up... it is the inverse of how deep it is. :-)

Is the length related to adding more hose pipe, at the same size the longer pipe the heavier the water gets slowing the flow.

A short shallow water flow fast. A wide shallow water flows fast. A small or wide long water flow slowed down from weight to push and can flood over.

In a MOSFET, the length of the conduction channel is related to its resistance, which is what slows down the flow. So it is like adding more hose of the same size, but I think the slowdown is due to friction. The heaviness has more to do with another relationship between force/velocity and current/voltage.
