Question

Two 0.68 Fµ capacitors are connected in series across a 10 kHz sine wave signal source. What is the total capacitive reactance?

Answer 1

`X_C=46.8 Omega`

Explanation:

If I remember correctly, Capacitive Reactance should be:
`X_C=1/(2pifC)`
Where:
`f` is the frequency
`C` Capacitance
For capacitors in series:
`1/C=1/C_1+1/C_2`
So `C=3.4xx10^-7F`
So:
`X_C=1/(2pi*3.4xx10^-7*10000)=46.8 Omega`
