CAPACITOR FORMULA BASICS AND TUTORIALS

Capacitor Formulas
Nomenclature: C = Capacitance in μF
V = Voltage
A = Current
K = 1000

1) Capacitors connected in parallel: CTotal = C1 + C2 + C3 + - -

2) Capacitors connected in series:
CTotal = C1 x C2/C1+C2 For two capacitors in series
CTotal = 1 For more than two capacitors in series
1/C1 + 1/C2 + 1/C3 + - -


3) Reactance – Xc (Capacitive)
a. Xc = 106/(2πf)C
b. Xc = 2653/C at 60HZ (1μF = 2653 Ω)
b. Xc = KV^2 x 10^3/KVAR

4) Capacitance – C
a. C = 106/(2πf) Xc
b. C = KVAR x 10^3/(2πf)(KV)^2

5) Capacitive Kilovars
a. KVAR = (2πf)C (KV)^2/10^3
b. KVAR = 10^3 (KV)^2/Xc


6) Miscellaneous
a. Power Factor = Cos θ = KW/KVA
Tan θ  =KVAR/KW
