Physics

Use the exact values you enter to make later calculations. PartA A group of students performed the same \"Ohm's Law\" experimentthat you did in class. They obtained the following results: TrialΔV (volts) I (mA) 1 1.00 4.4 2 1.90 8.4 3 3.10 13.3 4 3.90 16.8 55.10 22.2 where ΔV is the voltage difference across the resistorand I is the current traveling through the resistor at the sametime. (a) Analyze the data. (You will not submit this spreadsheet.However, the results will be needed later in this problem.) (i)Enter the above data into an Excel spreadsheet. (ii) Make a plot ofthe voltage difference vs. current. Hint (iii) Use the trendlineoption in Excel to fit the data of voltage difference versuscurrent to get the slope and intercept. Hint (b) Determine theslope and y-intercept of your graph, and report these values below.(Use ohm for Ω.) slope = y-intercept = Part B Your mischievous labpartner takes the resistor that you just experimented with andassembles it in a network with one other resistor and places theminside a black box. He challenges you to tell him the configurationof the resistors inside the box. Being an industrious physicsstudent you connect the leads of the black box to your powersource, voltmeter (in parallel), and ammeter (in series) and takethe following simultaneous measurements. ΔV (volts) I (mA) 4.2811.5 Use the above measurements to find the equivalent resistanceof the arrangement. (Use ohm for Ω.) Req = Based on your value ofthe equivalent resistance, what must the arrangement be? in seriesin parallel Part C Now that you've answered his challenge, your labpartner asks you to give the resistance of the resistor that headded to the one you experimented with. Using the information youobtained in parts A and B, predict this value of the resistance ofthe second resistor.
