what is the formulacalculating Xc?

Answer 1

xc capacitance is 1/ 2 pie fc

xc leads remember

f=frequency
c=capacitance

XL= 2pie fl

l=inductance which lags

this should give you the answer youre looking for. Another equation you may find useful is z=r squared +xl-xc

z=total impedance
r=resistance
xl=inductance
xc=capacitance

Something you may later go on to do with xc and xl

Answer 2

Xc is usually the abbreviation for capacitive reactance.

Xc = 1 / (2 x PI x f x C)

Answer 3

Its Capacitive Reactance. Reactance is denoted by the symbol X and is measured in ohms.
If X > 0, the reactance is said to be inductive.
If X = 0, then the circuit is purely resistive, i.e. it has no reactance.
If X < 0, it is said to be capacitive.
Xc=1/wC=1/2pifc
where XC is the capacitive reactance measured in ohms
ω is the angular frequency, measured in radians per second
f is the frequency, measured in hertz
C is the capacitance, measured in farads

Answer 4

Xc = 1 / Cω = 1 / C x 2 x π x f
ω = 2 x π x f

where,
Xc - is the capacitive reactance measured in ohms
ω - is the angular frequency, measured in radians per second
f - is the frequency, measured in hertz
C - is the capacitance, measured in farrads

Answer 5

Xc = 1 / (2 ¶ f C) where :-
f = frequency in hertz
C = capacitance in farads
¶ = 3.14

Answer 6

i assume you mean reactance (resistance) of a capacitor?
if so 1/(2*PI*f*c)

PI = PI
f = frequency
c = value of capacitor in farads ie 1nf = 1*10^-9
