as part of a physics practical write up i have to measure the temperature of a light bulb envelopes temperature as the voltage increases.
first ... am i right in thinking a type J exposed thermocouple would do the trick for this?
if so, i heard something about one end being cold, to maintain a constant pd ?
second (most importantly)...am i right in thinking that a graph of V against Temp would be a straight line not through the origin?
thank you :)
p.s. already looked on the net for this and rly can't find n e thing on either point :S
