Lab #1 Follow the instruction and procedures in the Student Manual, unless specified differently in this note. Reading: Class 1 and Lab 1 in Student Manual (SM) To 1.9 in The Art of Electronics (AE). Lab #1 1-1 Follow the instruction for this part. When you present your data, try to make graphs. Verify Ohm’s law (at least 2 resistors) and compare the known values of the resistance with what you measured through the Ohm’s law (slope in I-V graph). Answer the questions posed in Effects of the instruments on your readings. To estimate the error in “a quantitative view,” you need to measure the internal resistances of the DVM in ammeter and voltmeter mode, and calculate their effect on the measured voltages and currents. You can measure the internal resistance of the voltmeter by constructing a simple voltage divider. Ask the instructor if you cannot figure out how to measure the internal resistance. You can measure the internal resistance of the ammeter by applying a voltage to it (put a 1k series resistor to avoid excessive current) and measure the voltage drop across it with a 2nd voltmeter. Try to measure the internal resistance at different current sensitivities. 1-2 Follow the instruction and answer all the questions posed. Plot the current vs voltage for the lamp. 1-3 Follow the instruction and make plots with both linear and semi-log scales. Measure with both positive and negative voltages from the power supply. Additional question: What is the role of 1k resistor in the circuit? You do not have to give answers to the questions posed on p.28. 1-4 Follow the instruction. Very important to understand a voltage divider. 1-5 Get familiar with the oscilloscope (OSC). You do not have to write this part in the report. 1-6 Get familiar with the function generator (F/G). You do not have to write this part in the report.
