Verification of Stefan’s law

1.Make connections to complete the circuit.
2.Slide the power to ON mode.
3.Increase the voltage from 0 V with an increase of 0.5 V till 9.5V.
4.Measure the corresponding current in ammeter.
5.Fetch the values of current and voltage in Table 1 after every step.
6.Take 10 observations.
7.Decrease the voltage from 10.0 V with a decrease of 0.5 V till 1.0 V.
8.Fetch these values of current and voltage in Table 1.
9.Take observations from Table 1 and place them in Table 2 by the Fetch button.
10.Values of LogP and LogT will be calculated.
11.Plot graph between LogP and Log T by plot data button.
12.Calculate the slope of the graph
