Electronic Laboratory Practise - Lab Report Example Therefore, the combined resistance is given by In this report, knowledge and experience in the use of essential laboratory equipment was acquired. The use of the oscilloscope, the signal generator, the power supply and digital multimeter were used to understand applications of various electronic circuits. The finite accuracy of the laboratory measuring instruments was equally demonstrated. The color coded resistors were read to establish the resistance of the resistors. After the resistance was measured using a digital meter and it was then confirmed whether the results depict similar resistance. The resistances measured are approximately equal with slight variation that is due to manufacturers errors that cannot be avoided in the manufacturing process (Purrington, 1997). The tolerances provided define the appropriate limit of acceptable resistance. For the 5 ohms resistor (5 Â ± 0.05) therefore 4.998 is within the range. Similarly, the lower boundary for 22 ohm resistor is (22Â ± 1.1) while the 20.9 ohms lower boundary lies within the range. The likely estimate of the voltages when 5 ohms and 22 ohms resistors were connected to 6.0 V supply to create a potential divider was determined theoretically. A digital multimeter was connected across each of the resistors and voltages obtained were compared. The results obtained were recorded as shown. From the results obtained, it is clear that the larger resistor receives the greatest share of the voltage in a voltage divider. Internal resistance of the multimeter adversely affects the measured voltage in cases where large current is drawn (Hector, Lein, & Scouten, 1943). In this case the amount of current drawn is relatively small hence there is no significant effect on the measured voltage. The current through the two resistors which were in parallel was determined theoretically and
