Gday everyone,
I need a bit of assistance with a math problem.
If I have a 4.9uF Capacitor used in parallel across an Inductive circuit to improve the power factor on a 230v 50Hz circuit.
If I then Inject a 1050Hz signal into this circuit how much current will the Capacitor see.
I have so far:
The Current through the Capacitor for the 50Hz signal is:
Xc= 1/ 2*pi*f*C
= 1/ 6.28*50*.0000049
= 1/.00154
=649.3 Ohms
Ic= Vc/Xc
= 230/649.3
= .354A
Now for the 1050Hz signal I get
Ic = 7.43A
Do I now just add these two together so I get
7.43A + .354A = 7.784A ?
I tried to check this with LTspice but I only get 7.43A at the Capacitor & not the sum of the two currents together. So now I am a bit confused as always?
Cheers
