Today we performed an experiment using Photo voltaic cell. We used it to measure different voltages and intensities. We moved the light source at several times and also swiched the light key to low, medium and high. We found out that on high the voltage and intensity was higher than on medium and low. The same thing happened to the distance. When the sources were near the voltages and intensities were bigger.

Here is our data at low, medium and high light brightnesses

On Low:	voltage 0.52417	Intensity 68	On Med:	Voltage 0.48568	Intensity 82	On High:	Voltage 0.57549	Intensity 96

We graphed the Voltage vs Intensity and the result was a straight line. As voltage increased the intensity increased vlotage-vs-intensity1
