Average/RMS Values of a Rectangular and Ramp Function

ohdrayray

1. The problem statement, all variables and given/known data


2. Relevant equations
I_rms = [itex]\frac{I_m}{\sqrt{3}}[/itex]

3. The attempt at a solution
I'm lost on how to do a completely, whereas for b. I can find the I_rms:
I_rms = [itex]\frac{6}{\sqrt{3}}[/itex] = 3.46 mA
and the average, I'm guessing is 6/2 = 3 mA?

Thank you in advance!

This is not an exercise you do in your head.

To find the RMS: you take the square root of ..... the average value of ..... the graph of one cycle of the waveform SQUARED.

So you draw a new graph, this time plotting instantaneous V² vs. time
Then determine the area under that curve, and average it over the whole cycle.
Then take the square root of this average value.
