Question

RESISTOR VALUES: R1=1k, R2=2k, R3=3k, R4=3.9k, R5=5.1k, R6=6.2k, R7=6.8K

NUMBERS: 2, 4, & 5

1 Short AB, as shown in Figure 3 - 2 (a). Use mesh analysis to calculate the voltage across each resistor and the current through AB, IAB 2. Leave AB open, as shown in Figure 3 - 2 (b). Use nodal analysis to calculate the voltage across each resistor as well as the voltage across AB, VAB 3. Find Thevenin's and Norton's Equivalent using the results from the previous two steps. 4. Connect a resistor between nodes A and B. Use Thevenin's theorem to calculate the current through this resistor for the following 3 resistor values: 1 kQ, 2.2 kQ and 4.7 k 5 Leave AB open. Find the voltage across AB, VAB for the following 3 cases: a. E is turned on while both E2 and E 3 are turned off b. E2 is turned on while both E1 and E3 are turned off; E3 is turned on while both E1 and E2 are turned off. C. Add the above three voltages. What have you discovered? Provide a detailed explanation of your discovery. A AB R2 Re R1 R4 R3 R6 R7 E 12V E2 10V E3 5V (a) WW ww wWw A VAB VB=V3 + VA=V R2 Re R4 R1 R7 Rs R3 E 12V E3 5V E2 10V (b) ww m W
