1. Consider the dual supply circuit of Figure 6.1 using V1 = 10 volts, V2 = 15 volts, R1 = 1.5 k, R2 = 2.2 k and R3 = 10 k. To find the voltage from node A to ground. superposition may be used. Each source is considered by itself. First consider source VI by assuming that V2 is replaced with its internal resistance (a short). Determine the voltage at node A using standard series-parallel techniques and record it in Table 6.1. Make sure to indicate the polarity. Repeat the process using V2 while shorting VI. Finally, sum these two voltages and record in Table 6.1. 2. To verify the superposition theorem, the process may be implemented directly by measuring the contributions. Build the circuit of Figure 6.1 with the values specified in step 1, however, replace V2 with a short. Do not simply place a shorting wire across source V2! This will overload the power supply. 3. Measure the voltage at node A and record in Table 6.1. Be sure to note the polarity. 4. Remove the shorting wire and insert source V2. Also, replace source VI with a short. Measure the voltage at node A and record in Table 6.1. Be sure to note the polarity. Table 6.1 Source V1 Only V2 Only V1 and V2 VA Theory VA Measured deviation R1 Www Figure 6.1 A R2 V2 www.
