He discovered Joule's law in 1840[1] and hoped to impress the Royal Society but found, not for the first time, the he was perceived as a mere provincial dilettante. When Sturgeon moved to Manchester in 1840, Joule and he became the nucleus of a circle of the city's intellectuals.

Experiment: Joule’s Law of Heating. PRELIMINARY Questions. 1) A thermally isolated container holds 50 mL water. A 5 resistor, connected to a 10 V power supply, is placed into the water and the circuit is turned on for 5 minutes. During this time heat generated by the resistor is absorbed by the water, which heats up from an initial ...

Joule’s law of heating: It states that the heat produced in a conductor is directly proportional to (i) the square of the current I through it (ii) proportional to its resistances R and (iii) the time t for which current is passed. Mathematically, it can be expressed as H = I2Rt joule = I2Rt/4.18 cal or H = VIt joule …

To verify joule’s law. Why was a fixed mass of water used throughout the experiment? Given that the mass of water in the calorimeter was 90 g in each case, and assuming that all of the electrical energy supplied was absorbed by the water, use the graph to determine the resistance of the heating coil.
