Vdt = 10 volts
Vdf = 2 volts
Vdbc = 8 volts
Es = 240 volts
Ebp = 238 volts
El = 230 volts
%Vdt = 4.16 volts
%Vdf = .83 volts
%Vdbc = 3.33 volts
Note when using these formulas, enter %Vdt % Vdf %Vdbc as a decimal.
So 4.16% becomes .0416, .83% becomes .0083, and 3.33% becomes .0333.
Use your % key on the calculator to move the decimal two places to the right. Neat, eh?
