5. To cause subtle failures because they know SCR-type SSRs don’t current share well.

I expect this homework was assigned for a reason so you would have to go look up these things and learn a bit about RF signal detection and field strength measurement.

Ultimately everything is analog. However, there are certain regimes where it makes sense to not burden us with analog minutia and instead concentrate on binary logic. As a result, different specialties have evolved. Worrying about what exactly to call a particular circuit is pointless…

That’s just pedantic silliness. Get over youself.

Common usage defines the language. Yes, the charges flow. But in english at least it’s also fine to say the current flows. What verb would you use to describe what the current is doing otherwise, “exists”?

The same thing holds true for a…

There were tubes that can do a few Watts. The reason I mentioned the 6L6 is because it was very popular and if anything is still available today that would be high on the list. It is probably higher power than you need, but does that really matter?

The reason for two of them is this makes a…

You didn’t say why you are trying to build a tube amp. Is it because you want to learn or play around with these old things, or is this a audiophool religious thing?

In any case use a pair of 6L6 in push-pull configuration with a output transformer. With the right transformer, those can handle…

Charles, I think you are right to be skeptical of this answer. This looks like someone blindly plugged numbers in to a formula without bothering to think what the math means and what constraints might apply.

The formula with the exponent of 10 is obscuring what is going on rather than…

There is reasonable background and motivation of power factor control in a paper I wrote about a particular PFC technique. See http://www.embedinc.com/pfc

You apparently want to drive some LEDs using PWM. There are lots of ways to do that. For many applications a microcontroller is a good way to do that since it also has the capability to compute what the PWM duty cycle should be. Many micros have PWM hardware built in. PIC is Microchip’s brand…

Why? This makes no sense unless this is just a homework assignment. Build something you want to have. If you’re really into this, there should be lots of things you wish you had or idea you’ve been wanting to try out.

I don’t get building any project just for the sake of building a project.
