How the Angle of a Solar Cell effects the Voltage Produced
Introduction:
In this experiment, I will be experimenting the effect of adjusting the angle of a solar cell relative to the direction of light and the voltage produced based on the angle change.

Factors:
Some of the possible factors that could affect my experiment are * -------------------------------------------------
The angle of the solar cell. * -------------------------------------------------
The distance of the solar cell from the light source. * -------------------------------------------------
The intensity of the light source.
I will change the angle of the solar cell and use this as my independent variable, going up in 5 increments and measuring the

As current is the amount of charge passing one point in a second, and the more photons hitting the solar cell, the more electrons that are able to flow, which increases the current. Due to this as the angle increases this causes an increase in current, as current is directly proportional to voltage when resistance is constant, the voltage would also increase.

Method:

Apparatus: * Solar cell to adjust the angle of and generate a flow of current. * Light box to produce light. * Protractor to measure angle of solar cell. * Resolution of 0.5˚. * Multimeter to measure voltage. * Resolution of 1mV. * Clamp stand to hold clamp. (x2) * Clamp to hold solar cell and to hold protractor. (x2) * Leads to connect the solar cell to the multimeter. * Meter ruler to measure the distance of the light source.

Risk: * One risk with this experiment is that we will have a bulb,
