EXPERIMENT 2 Measure the actual value of each resistor and record in Table 2.1 V1 R1 R2 R3 R4 R5 R6 PART A 1. Construct the circuit shown in Fig. 2.1 CONNECTIONS 1. Commence at point A and measure the potential difference between each successive pair of lettered terminals for Mesh 1. i. e. A-B, B-C, C-D and D-A. (Note: DMM’s probes have to be placed consistently.) A 2. Record down the measured values in Table 2.2. B Reference points A-B B-C C-D D-A Measured Values Potential Sign (+ or -) Difference (V) Theoretical Values Potential Sign (+ or -) Difference (V) 0.596 V 7.558 V 10 V + 1.846 V - A C 4. Measure the potential difference for the points AC, CE and EA. Verify Kirchhoff’s voltage law using the displayed values. (Note that VCA is actually VC – VA). What can be deduced from this condition? Record the measured values in Table 2.3. Reference points A-C C-E E-A Measured Values Potential Sign (+ or -) Difference (V) Theoretical Values Potential Sign (+ or -) Difference (V) 8.154 V 9.345 V + 1.191 V - 4. Measure the potential difference for the points AC, CE and EA. Verify Kirchhoff’s voltage law using the displayed values. (Note that VCA is actually VC – VA). What can be deduced from this condition? VAC + VCE + VEA = -8.154 + 9.345 – 1.191 = 0 V x z PART B y 1. Measure the branch currents entering node A by placing ammeter as shown in Fig. 2.1. 2. Record the magnitude and the direction of the current as indicated by each ammeter in Table 2.4.
