How can you experimentally verify the Joule-Lenz law?
November 9, 2020 | Education
| You can experimentally check the Joule-Lenz law using a calorimeter filled with water, a stopwatch, a heater, a thermometer, a rheostat, an ammeter, and a voltmeter. It is necessary to connect the electric circuit and the heater to the mains and by changing the current through the heater using a rheostat, measure the water temperature in the calorimeter using a thermometer at regular intervals, measured by a stopwatch.
