PROCEDURE
1. Set up the circuit arrangement as shown in circuit diagram or apparatus arrangement.
2. Note the least count of the ammeter and voltmeter.
3. Find, if any, zero error of the ammeter and voltmeter and record it in table 'A'.
4. Plug the key/switch on the battery eliminator and adjust the rheostat by sliding its variable terminal
till the ammeter and the voltmeter show a reading.
5. Note the readings of ammeter and voltmeter in table 'B' Take out the plug or switch off the battery
eliminator for a moment.
6. Repeat the step 4 and 5 for the different values of current by varying the sliding terminal of rheostat
V
7. Tabulate all the observations in the observation table 'B' and find the ratio of
І
observations. Find the mean value of R.
8. Plot a graph by taking I along y-axis and V along x-axis or V along x-axis and I along y-axis.
