I need to " design an experiment to investigate the relationship between the resistance of an electronic equipment and the temperature of its enviroment"

We don't now was the electronic equipment is and how do i change the temperature, can u help me?

nah, i think the electronic equipment is a capactior, but im not sure, as he only showed we from a distance and would give us a closer look. I cant think of a way to change the temperature, and the lab doesnt have an air-con. I'm also sure that he isnt going to give use liquid nitrogen.

shove 5V into a thermistor (a resistor that changes its resistance according to temperature) and series it wif an ammeter and watch the current change.. therefore resistance change due to V = IR

u can change the temperature by blowing a hair drying or something at the thermistor.. or juss holding it in ur hand...

btw..a thermistor only cost around 50c at like jaycars..

we are getting the electronic component but u will have to repeat the experiment hence a consistant temperature is requried
