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.)

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.

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
