Hi all,

I'm struggling with these questions for this circuit as the equations I have in order to work out impedance etc all seem to need the value of the capacitor so I'm at a loss now and was wondering if there was a way to work out the capacitor value or if there was another equation I could use in order to not need it?

How about with the values given, you work out the voltage across the resistor, and hence deduce the voltage across the capacitor.
Then you can use a formula to calculate the capacitor value from the voltage across it, the current through it, the frequency etc etc.
Not that I've done any of this for the last 55 years so Could be wrong

Thank you, I'll give it a try
