Ok. So I am currently doing a term on thermoelctrical physics and was told to perform an extended experimental investigation on this topic. The teacher has given me some examples but none seem to jump out to me. I was wondering in\f anyone has a few topics which are relatively advanced for a year 12 physics class but isn't too advanced. These are some of the examples that the teacher has given us: Are thermal and electrical conductivity related? Does the temperature of a flame affect the dielectric constant of air? What factors affect the effectiveness of an insulator? What is the most effective insulator? What are the factors that affect the conductivity of a wire? Does colour affect absorption and emission of electromagnetic radiation? Which colour of roof tile keeps a roof cavity cooler? What are the factors that affect the efficiency of a solar panel? Are compact fluorescent light bulbs really more efficient than the old incandescent bulbs? What expensive is battery power (compared to mains)? Something similar to these but more advanced would be great, Thanks guys.
