I don't know about voltage, but in maths it is the hypotenuse of a
right-angled triangle!

What is the basis of this formula for working voltage ?
sqroot(a^2 + b^2)
thanks,
Brian
That is the formula for the geometric sum of 2 RMS quantities. For example,
if you have a primary circuit that has a working voltage of 230Vrms and a
secondary circuit with a working voltage of 32Vdc, the RMS working voltage
BETWEEN the two circuits is determined with the formula, giving you 232
