Experimenting with RC Combinations: Finding C & R Values

[Clipse]

This is an experiment Ill have to write up later, unfortunately I was out for 2 weeks of lectures due to illness. This is the experiment;

Find the values of capacitance C and resistance R in a series combination, given he following apparatus;

1. the unknown RC combination (both in the same enclosed box),
2. a known, reference resistor, Rref,
3. a variable frequency signal generator (0-1000Hz),
4. a digital multimeter


An equation involving impedance that I can think of off the top of my head is;

I = (Emax . Sin(wt + &))/ |Z|



I really am completely stumped guys... I just need to know how to do the procedure and then the calculations should be ok... Any input would be GREATLY appreciated.

This seems to be a homework problem, so it is in the wrong forum. Anyway, how do R, C and frequency affect phase?
Don't forget to consider the output impedance of the generator in your calculations.

You must show some work before we can help you.
