Start with the definitions of Vavg and Veff and show your best attempt.Find average value and effective value of V and form factor.
In calculating Vavg, why are you only integrating the first part from 0 to pi/2?Form factor is the ratio of effective value to the average value.
I am confused while putting the value of T.
Hi,Form factor is the ratio of effective value to the average value.

Depending on where he is in the material, they may not have gotten there yet. The rms is not the definition of effective voltage, it followed from the definition of effective voltage.Hi,
Quick note...
You know what RMS stands for right?
It stands for "the Root of the Mean of the Square". The proper math follows from that and i am not sure you are doing that yet.

He might have. But was he calculating RMS, or what we calculating effective voltage based on the definition? Both will end up with the same setup result, so the only way to tell is from how the setup was done  was it does by regurgitating an RMS formula or from setting up the problem to find the average power into a resistive load over one cycle?Hi,
I thought i saw in one of his papers that he was trying to calculate the RMS value but it did not look like the right calculation exactly. The writing was a little small though.

I only looked at the first paper because once I find an error I generally figure there's not much point going any further until that issue is resolved. If I could get the TS to grasp that notion, he could save everyone, himself most especially, a lot of time pursuing work that is past repair.
I will absolutely take your word for it. Again, I didn't look at the work beyond the first major mistake as I would rather the TS learn to check their work incrementally instead of just blindly bashing through to an answer that was doomed to not be a solution from literally the second line of their work and for which just a bit of asking, "Does it make sense thus far," could have saved all that effort.Hi,
Well i seem to recall seeing Vrms written down with a formula to the right that is not the whole calculation for an RMS value
First part is symmetrical function and average value is zero so for complete cycle in symmetrical so i only took half the time which is equal to pi/2, but i think since i only took half should i multiply it by 2 to get averwge for complete cycle? Did you mean that in second part aswell i should integrate from 0 to pi?In calculating Vavg, why are you only integrating the first part from 0 to pi/2?
What i know is it stands for root mean square.Hi,

That would be 1?
How can that be correct.?That would be 1?
30 mph, oh and in first fig avg would be .5, it was silly me to say 1.How can that be correct.?
Consider this alternative.
Say you drive your car at 60mph for 30 minutes then stop for a further 30 minutes, what is your average speed over the hour.???
