060214 Physics 4B*

This was an experiment using ac and dc power. The left light box is AC, then the DC will be the dimmer box on the right light box.

 This is picture of the first experiment with a 200 micro ferret capacitor.

This is the data collected when the current and and the voltage was calculated through the capacitor. According to this graph I would saw that the current and potential are in phase.  

The data above shows  the capacitance reactance.  First we calculated the V(root mean square) which is  V max / sqrt(2) and I(root mean square) which is Imax/sqrt(2). where capacitance reactance = V(rms)/I(rms). Theoretical. We experimented using frequency and a capacitor. Capacitance reactance is found using [1/(2*pi*f(frequency)]. Conclusion higher frequency would give a better data or lower error.  

                                      
 This is a picture of experiment 2 where we used a inductor. The function generator started to over current so a 100 ohm resistor was added.  

  This was the graph found using the inductor. I would say that the current and potential are out of phase.

The calculations shows the inductance reactance the calculations for capacitance reactance. V(rms)= Vmax/sqrt(2). I(rms)=Imax/sqrt(2) So inductance reactance = V(rms)/I(rms) this is the theoretical calculation. The experimental calculation = 2*pi*f(frequency)*L.
