## Xc = 1/2 pie fC

Xc = _1_

piefC

Capacitive Reactance (Xc) in Ohms

Frequency (f) in Hz

Capacitance (C) in Farads in a electrical circuit

Taking 2pie as equal to 6.284

a) how i make 'f' the subject?

b) how do i calculate f when Xc = 318.47 Ohms, C = 1uF (equivalent to 1x10exp-6F)

im really stuck
