AIM: To get familiar with basic circiuts, resistors and their
colour codes as well as  the instruments in the lab and there uses.

PROCEDURE 1: Using 5 different resistors, the colour codes were read and the results were recorded. Using the same 5 resistors, the results were checked using an ohmmeter scale that was taken using the multimeter the results were again recorded. The results were then placed in a table and compared.

RESULTS:
RESISTOR NO.     NOMINAL VALUE     MEASURED VALUE     PERCENTAGE
DIFFERENCE
1     18000 +/-10%     17760     -1.3%
2     3300 +/- 10%     3660     +10.9%
3     1000 +/- 10%     1038     +3.8%
4     4700 +/- 10%     5060     +7.6%
5     2200 +/- 10%          bad resistor

CONCLUSION 1: There was a difference between the nominal value and the measured value. All except resistor 2 and resistor 5 (which was bad) were within the tolerance band.

PROCEDURE 2: The power supply was set to give 3 volts. The multimeter with a voltage scale was then used to measure the exact voltage that power supply was supplying.

RESULTS: The multimeter read about 4-4.5 volts. And it was difficult to adjust the power supply to get th...
