A) Build one circuit with one battery and 4 resistors, all with different values of resistance and arranged in at least two loops. Include picture of the circuit in your lab report. Measure all currents through and voltages across all elements in your circuit (10 values total). Now calculate all the currents and voltages using the equations for circuits. Make a table with one column showing all the measured values and one column showing all the calculated values and one column with the percentage error for each value. B) Build one circuit with TWO batteries and 3 resistors (all different values), arranged in two loops, each loop with a battery and a resistor, and the third resistor shared by the two loops. Include picture in lab report. Measure all voltages and currents and calculate them. Arrange values in a table, just like in part A, including percentage error. Write a lab report with the following sections: Objectives. What is the purpose of this lab? Theory. What equations or physical laws are relevant to this lab? Procedure. Describe what you did. You can copy paste the instructions above and add pictures of the circuits you built. • Data&Calculations. Include here your calculations. For some labs include data in tables, and include graphs if relevant. · Conclusions and error discussion. Did you verify the theory? How big was the error? For a calculation of the error in Kirchhoff's loop law follow this example: Suppose the sum of all the voltages measured around a single loop is 0.1 -0.5 + 0.31 -0.2 +0.28 = -0.01 (theoretically this sum should have been 0). In this case the % error is calculated as follows: Sum of Positives (SP) = 0.1+0.31+0.28 = 0.6. Sum of negatives (SN)= 0.5+0.2 = 0.7. %error = 100% x ISP-SNI/SP = 100 %x (0.69-0.7)/0.69 = 1.45%
