Thanks for the lectures to: https://www.phys.hawaii.edu/~morse/P272fall10-20_pdf.pdf Now let's think about when the impedancy of AC current in phasor diagram is zero. It is when we make upperwise equation (VL-VC)/R=1-(-1)]/1, where V fell out of eqn, now tan(fi)=2 which is fi=63.4deg, for this angle we have 2cos(fi)=sin(fi), where 2=sin(fi):cos(fi) which is 2=tan(omegaT+fi), which is 2=tan(2pif-63.4deg) which is 63.4=360freq-63.4deg, now look at what is freq for 126.8:360? it is 0.3=one third, why can we create 2pif+fi same as 2pif-fi? Look at phasor diagram Z vector==0 at VL-(-VC)=2 And where do we see such division of freqencies? As 1:3, yes, it is double slit experiment with one photon or one electron. What is even more interesting is equal 1:3 division for photon with what? Yes, zero impedancy Z :) Oh, you must make up your math ;) Picture:
