Electrical Circuit Analysis Lab, Study Guides, Projects, Research of Chemistry

Ohio State University (OSU) - MansfieldChemistry

A lab worksheet that guides students through the analysis of three electrical circuits. The worksheet includes data collection, data analysis, and discussion of the results. The data collection involves measuring voltage, current, and resistance in the circuits, while the data analysis requires calculating resistance, power, and plotting graphs. The discussion section asks students to interpret the physical meaning of the slope and y-intercept of the graphs, as well as compare the calculated and measured current in one of the circuits. This lab exercise is likely part of an introductory electrical engineering or physics course, providing students with hands-on experience in circuit analysis and the application of fundamental electrical concepts such as ohm's law and power calculations.

Appendix B: Step 2 - Data Analysis

For Circuit 1

  1. Calculate the resistance R in the last column of Table 1 using Ohm’s Law – equation shown below. Pay close attention to UNITS! (Remember from class that volts/amps = ohms). Show your work by hand for these calculations and include them in your submission of this worksheet (1 point). R = V (^) s I
  2. Completely fill in Table 1 (1 point). Table B.1: Circuit 1 Data Set Voltage VS (V) Measured Current I (A) Calculated Resistance R (Ω) 0v (^) 0 A 0 Ω 5v (^) .00003 A 166666.67 Ω 12v (^) .00010 A 120000 Ω 15v (^) .00013 A 115384.62 Ω 18v (^) .00016 A 112500 Ω

(amps) 0 1.0V (^) 0 A 000.00 Ω 5 1.0V 0.00001 A (^600000) Ω 7 1.0V 0.00003 A (^) 266666.67 Ω 9 1.0V 0.00005 A (^200000) Ω

  1. Plot Vs as a function of I (Vs on the y-axis and I on the x-axis) in Excel_._ Find the linear ‘Line of Best Fit’ and display the equation on the plot. Include a screen shot of this plot below for full credit (1 point). For Circuit 3
  2. Use the equations below to calculate the power across each resistor and the total power in Table 3. Show your work by hand for these calculations and include them in your submission of this worksheet (1 point). P 100 Ω = I 2 ∗ R 100 Ω P 200 Ω = V (^) 200 Ω ∗ I Ptotal = P 100 Ω + P 200 Ω
  1. Completely fill in Table 3 (1 point). Table B.3: Circuit 3 Data Set Voltage VS (volts) Measured Current I (amps) Measured V 200 Ω (volts) Calculated Power P 100 Ω (watts) Calculated Power P 200 Ω (watts) Calculated Power Ptotal (watts) 5v (^) .03mA 10v .00015 W .0003 W .00045 W 10v (^) .08mA 20.2v .0008 W 0.00162 W .00242 W 15v (^) .13mA 30.2v 0.00195 W 0.00393 W .00588 W
  2. Then, choose one row from Table 3 and use the quadratic equation below to solve for the current (I) flowing through the circuit. Show your work by hand for these calculations and include them in your submission of this worksheet (1 point). I 2 R 100 Ω + V (^) 200 Ω I − Ptotal = 0 NOTE: Only plug in the variables ‘Ptotal’, ‘R100Ω’, and ‘V200Ω’ – not ‘I’. We did already measure I, but we are using our Power calculations to compare our measured current (I) to the value you calculate in this step. Row 1: 1.) I^2 (166666.67) +10I-. 2.) (166666.67) I^2 +10I=. 3.) x=.00003 or -.
