calc relative mean deviation for R1 and graph

DATA: PART A. R11 ReadingV(volts)I (amperes) 10.9 0.Y5 1.45 0.35 3 3.0 2.7 3 12.6 Average Value R 1 12.a5 PART B. Circuit 12 Series | 0.00丫1 9 | aooy 0,00 Compute the mean deviation and the relative mean deviation for RI Plot a graph of the voltage versus the current. The voltage is on the vertical axis and the current is by the on the hozontal axis. Draw the best straight line determined hrough oalnl tho thn sraph. Remember, it is not necessary for the line to go The slope of this graph (line) gives the resistance R1 (V R1 XI). Calculate the se the Macintosh computer to analyze and graph the data. Switch on the Macintosh computer. A beep lets you know that it is ready. An Icon (small picture) will appear labeled Hard Disk. Move the mouse to open the File Menu at the top of the screen and click the mouse on the word Open. Open Hard disk. Its contents will appear on the screen. Click the icon labeled Cricket Graph, which will then be highlighted. Open Cricket Graph. Move the mouse to c the File Menu at the top of the screen and click the mouse on the word Open or quickly Double Click on the Cricket Graph Icon. The Cricket Graph program is now started. It will 2 take a few seconds for the program to be loaded. An emptý data window will appear on'which you can input data. Use the key board to input the data you want to graph. Label each column ll want on the particular axis (voltage, current). Click the mouse on the word Graph at the top of the nenu and move mouse nd click on the type of graph desired (Scatter Graph). A new window opens and asks what tables you want to appear on the axes. ew Grap h. Click the mouse on Curve Of Best Fit on the menu; click the desired Curve or Line. Chose the curve which best fits the points. You will simultaneously obtain the equation of the curve Experiment 7 Ohm's Las- Resistance in Series and Paralle

Answer 1

Your given data is very unphysical still I have done calculation using your data. Also in your data you are calcultinca R incorrectly since you need to divide V by I and you have done reverse there, have a look at my calculations:
