And that’s how I measure high voltage. I’d be very curious how you’ve done it, what probes you’d recommend and what your experience has been. Also, have you done any AC voltage measurements?

The r.m.s. value of an a.c. signal is equal to the value of direct current (d.c.) which would have the same effect or energy change as the a.c. The r.m.s. voltage of an a.c. signal is always less ...

4 \times 0.5\) \(V_{p}= 2.0V\) However this is not the effective voltage of the trace. A more useful measure of a.c. voltage is the r.m.s. or 'root mean square' voltage.
