Experiment No. / Amendment or additional information6 (a) / In Procedure,
7. Take another four records for pulse amplitude of 15 cm, 20 cm, 25 cm and 30 cm. Tabulate the results in Table B1.2.
8. Repeat steps 2 to 5 by stretching the spring at four different lengths. Tabulate the results in Table B1.1 as data sets 2 to 5.
6 (b) / Additional information:
Do NOT touch the glass surface of the lamp after use. It is VERY HOT !
8 / Part B:
In Procedure,
5. Connect the 6 V battery to a rheostat R and the voltmeter in parallel as shown in Fig. C13.2. Record the readings of the ammeter (I) and the voltmeter (V).
7. Plot a graph of the p.d. (V) across the rheostat versus the current (I) pass through the battery. Find the slope and the y-intercept of the graph. Hence, find the internal resistance and the e.m.f. of the battery.
Part C:
In Procedure,
8. Connect an EHT supply to the resistance box of resistance R and a milliammeter. (No need to connect the voltmeter !)
Set the resistance of the resistance box to the maximum value (10 M).
9. Switch on the EHT supply and set its voltage output to 1000 V. Record the readings of the milliammeter (I) and the resistance of the resistance box.
10. Repeat step 9 with the other values of R (between 10 M and 100 k). Tabulate the results. Find the reciprocal of the current (1/I) pass through the EHT supply. Plot a graph of R versus 1/I. Find the y-intercept of the graph and hence the internal resistance of the EHT.
