Planning I am planning to investigate the maximum power output of a solar cell (photovoltaic cell). As I will be using independent and dependent variables I will need to keep many conditions constant. The independent variables I could change are resistance of circuit, light intensity, colours of light and surface area of cell. My dependent variables I will need to keep constant are power, voltage and current. I have decided to change the light intensity because I think it is the biggest influential factor and it is also the one that can change the most. For example, when a solar cell is used to provide electricity to a home, it is attached on a roof. It is also the independent variable on which the whole solar cell operates. I will change the voltage of the light, and the distance away from the bulb of the solar cell. I will...
