Tutorial: Designing a Common-Emitter amplifier using QSpice

In this video, I show one method of how to design a common-emitter amplifier with an NPN BJT, the MPS8098, using the QSpice simulator.

Awesome tutorial !.....cheers.

What would need to change if the load resistance is much lower? For example, a speaker that is only 5 ohms. Great video!

I probably wouldn't use this particular circuit to drive a speaker because of how much power that would require. In theory, you could make Rc 5 ohms and use a really beefy transistor + heat sink. With 5 ohms at 15V, that's going to have to dissipate about 45 watts, and the transistor will be sinking 3A of current.
