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.)
