Primary RMS Current calculation

Hi All,

        I have received a number of inquiries about primary circuit RMS
current and using MMCCalc for different types of capacitors.  MMCCalc displays
the current:

The RMS current is calculated using the formulas in MMCPower4.html.  The
equations for resistance of a single cap (Rcap) and power dissipated in a
single cap (Wo) can be used to find current by simply using Ohm's law.

P = I^2 x R  ==>  I = SQRT(P / R)

So the RMS current in a single cap (which is the same for a single string)
is:

Irms = SQRT (Wo / Rcap)

The Primary RMS current is simply that number multiplied by the number of
strings

Iprms = SQRT (Wo / Rcap) x Nstring
