Let’s work exclusively with rms quantities: 12 Volts peak-to-peak is 6 Volts amplitude, and dividing by the square root of 2 (~ 1.41), we get an rms voltage of 4.24 V from the source.
Just to raise awareness among interested students here on CD how AC calculations differ from the simple V=IR DC stuff they learned, and maybe motivate some to get into studying it.
It almost sounds like a motor controller to motor, if the wave was square instead of sine.
Yeah, it was inspired by some recent discussions here involving motor inductance and how that affects power calculations.
Seriously though, it is pretty interesting, especially once you get in to reactance, systems can do weird things. I find students tend to get very interested in inductive backlash (which is what I call the tendency of inductive loads to cause interesting voltage fluctuations in an attempt to maintain current flow)
Eww math. I did too much of that today already, load calculations and voltage drops, motor conductor sizing, I slacked off on some bids and paperwork this week :rolleyes:
Students, while math is boring and you find it stupid (not that I blame you, no one really gives a darn where X is, it’s more fun when you can apply it and make money off it) it is important if you want a technical career.
