The Challenge: Make a Thermometer
Page: 1 2 3 4 5 6
The second type of thermometer we made was a resistance thermometer.
This device uses changes
in the electrical resistance of a metal to measure temperature differences.
We made a voltmeter then put the metal to be tested within a Wheatstone
Bridge circuit which enables you to measure changes in electrical
resistances very accurately and hence temperature differences.
