You don't get away with it that easy so how many VG is it possible to have within an AC signal What is 3 phase electric
or is that all DC really is, just an adjusted AC signal, which seems to make sense in my world
Now we're going to look at converting a DC signal to an AC signal.
Give me a bit to make the sim.
just thinking outl oud, give me time to figure this out, so see sim MUTT17, I took R1 out to see what would happen, now we have a perfectly DC biased signal, can't even see a ripple, however the V went up from about 1.4 to 1.85, so the cicuit was working as so, please correct me where I have misunderstood:
The rectifier was clipping the - side of the signal (below gnd) the resistor was altering the V, the cap was finishing with smoothing the signal out
So how do you know how much load you could put on that if your just suppyling a given signal or is that for later?
I haven't gone for the night, just needed to clear computer for Lou.lol
So we can alter the internal resistance on sim, what does that mean with components?
I usually don't concern myself with the internal resistances of the power sources because I don't usually hook them up in series OR parallel.
For instance, with the AC sig gens, if I were to hook them up in parallel (as in the 2 AC Frequencies example sim) with an internal resistance of zero (0), it would return an error indicating an over-current situation (A short) between the two of them, and the simulation would fail.
I had a little plumbing problem (I'm on well water) that needed tending to. Just now finishing up.
I'll be back at it here thinking nothin' but "tronics"tomorrow. I promise.
Good morning, Graham.
While I'm slaving away at the AC issue, what do you think of a re-cap of what we've covered thus far?
How about you letting me know what you feel pretty solid with up to now and what may still be "foggy" for you.
Let's start with (just basic definitions of (and/or purpose) of the components we've covered:
battery,
resistor,
capacitor.
then DC, what is it and how is it useful
Then AC, same question
then how the two can interact.
This is NOT a test!!. Just an exercise.
(And it buys me time...)
Chortle...
Sounds perfect, I could do with something simple for five minutes after this morning, what can I say about a battery, it supplies DC power
A resistor can be used to create a load (current-'I') on a sim, they vary in size & shape & colour, the readings are in Ω on ameter, the value is dependant on the circuit, not so important on sim for teaching but when we get to do something as a real circuit, they will need to be worked out properly
They only work on Ac as it works on both signals - & + of ground, one side they charge up & the other they release power to smooth the voltage.
There was also that other cap that looked flat sided but round but I'm presuming that works on the same principle just a different value, so these too can come in variuos shapes & colours
direct current, basically a stable (noise free) voltage supply with only a single wave, I would have even gone as far to say that it is just an AC signal manipulated but if it comes off a battery it is a stable supply, DC has a flat waveform until changed by AC
AC current is alternating current which oscillilates back & forth giving us a - & + waveform either side of ground (feel free to correct me up if these are two seperate things) Waveforms can be mixed in multiples to create waves within waves, altering the frequencies, it is measured on a sillyscope by the p-p ampitude of the voltage & time via frequencies, the pahes alters the cucle of the wave.
i take it inductors work on the same principle as caps but for current
What happened to KISS, haven't seen him on here for a few days
Five weeks to get that far, is that good or bad?
