here's a question we got given from our teacher (AS level) Design a laboratory experiment to investigate how the resistance of a house brick varies with temperature in the range 20 to 800 degrees centegrade. it is known that the reststance on the brick is very high. the brick is of a non-uniform shape, and the resistance is to be measured from the two end faces. personally i dont know where to start. or go on to. any ideas people?!
