I already found the answer;
If what I think is right, then at very high frequencies the reactance of the capacitor goes down drastically,
so almost all of the current flows through the capacitor. The voltage over the parallel resistor and capacitor is then given by V=I*Xc with Xc the reactance...
Homework Statement
We have built a circuit with an ac source containing a resistor in series with a parallel RC combination, we have measured the voltage across the first resistor and the voltage across the RC combination with a high and a low frequency.
80Hz: V0 = 2,325 V en Vm = 2,780 V...
