Substituting Functions

You can change the formula for Parallel resistance to Series resistance, Series Capacitance or Capacitance Reactance , by making changes only to the black text of JS1.html
Declare variables as required.

Parallel Resistance
1/Rt =  1/R1 + 1/R2 + 1/R3;

Series Resistors
R(t) = R1 + R2 + R3 + R4 + R5 + R6

function mathgeneral(){
R(t) = R1 + R2 + R3 + R4 + R5 + R6; Alpha = ("Rtotal is "+Rt);
document.B1.T1.value = Alpha}

Series Capacitors
1/Ct =
1/C1 + 1/C2 + 1/C3
function mathgeneral(){
recipCt = 1/C1 + 1/C2 + 1/C3;
Ct = 1/recipCt ; Alpha = ("Ct is "+Ct);
document.B1.T1.value = Alpha}

Capacitance Reactance(Xc)
Xc = 1/(2*Pi*F*C)   Pi = 3.141, F = frequency, C = capacitance

function mathgeneral(){
Xc = 1/(2*Pi*F*C) ; Alpha = ("C is "+C);
document.B1.T1.value = Alpha}

Exercise: Develop a new program using functions above. Save (Safe As) giving each file its own name. Enter any values in variables that you like. Check your program results by performing same calculation by hand (with calculator of course.)
