I'm conducting a lab in which I change the distance of a lamp from a solar panel and use a multimeter to measure the resulting voltage. What type of relationship am I supposed to find? My results seem to indicate either a relationship with either a quadratic equation as its model or an inverse power equation as its model. Could someone tell me what would make sense here? My class is learning about electricity and circuits, but we haven't yet covered how the concentration of light is dispersed over distance, how that would affect the energy received by a solar panel, etc. Thanks!
