ElectricalMath on Instagram: "Let’s show why the rms (root-mean-square) value of a periodic, triangular current (or voltage) is the peak value divided by the square root of 3, and not the square root of 2 as is the case for sinusoids. Key learning moments from this walkthrough: 1) When integrating over one period, choose an interval that requires fewer piecewise definitions. 2) When evaluating a definite integral, see if there is any symmetry to exploit. Interpreting the integral as the area und
