EE 210L. Electro-Magnetic Foundations in Electrical Engineering Laboratory Report Experiment # __2__ Title: ___Experiment 2: Ohm’s Law and RC Circuit___________ Section # _________ Date Submitted: __3/9/2010__________ Pre-lab Questions: Answer for all pre-lab questions. It is required to copy the question and then provide your answer. You may use equation and illustration to enhance your description. You need to clearly label each question in the order same as that in the lab handout. You must study the pre-lab section before you make an attempt to answer pre-lab questions. This process is necessary and helpful to conduct the experiment. (20 points) 1. Measuring Voltage and Current In Part 1 of this experiment you will measure the potential drop across and current through a single resistor attached to the “variable battery.” On a diagram similar to the one below, indicate where you will attach the leads to the resistor, the battery, the voltage sensor, and the current sensor. For the battery and sensors make sure that you indicate which color lead goes where, using the convention that red is “high” (or the positive input) and black is “ground.” Reread the pre-lab description of this board carefully to understand the various parts. When you draw a resistor or other circuit element it should go between two pads (dark green areas) with each end touching one of the spring clips (the metal coils). Do NOT just draw a typical circuit diagram. You need to think about how you will actually wire this board during the lab. RECALL: ammeters must be in series with the element they are measuring current through, while voltmeters must be in parallel. 2. Resistors in Parallel In part 2 you will add a second resistor in parallel with the first. Show where you would attach this second resistor in the diagram you drew for question 1, making sure that the ammeter continues to measure the current through the first resistor and the voltmeter
