EE 442 Laboratory Experiment 4Introduction to the Principle of SuperpositionR14.7kR2i1''12VdcV2i3''10kR3i2''33kFigure 3 Circuit of Figure 1 with the upper source suppressedI 1 ’’ = __________I 2 ’’ = __________I 3 ’’ = __________D. Combine the solutions of parts B and C and compare with thesolution of part A.III.LABORATORY EXERCISES1. Connect the circuit shown in Figure 4 using the Agilent E3630A.(Make sure the tracking ratio knob is locked in the Fixed position;this position will guarantee that both the +20 and -20 V taps deliverthe same voltage magnitude with respect to the common tap.)4

Energize the circuit of Figure 4 and then measure and record thefollowing data:a. Ammeter readings A 1 and A 2 (compare with preliminarycalculations)A 1 = __________A 2 = __________b. Voltage across the 4.7kΩ and 10kΩ resistorsV 4.7 kΩ = __________V 10 kΩ = __________c. Voltage across the upper 12 Volt source terminalsV 12 V = __________3. Using the data obtained in Step 2, apply KVL by calculating the sumof all the voltage drops around the upper closed loop (remember totake the algebraic signs into account). Is KVL satisfied?4. Turn off the DC supply and reconnect the circuit as shown in Figure5.5
