Unformatted text preview: 8-11. Compute the effective resistance between the given points. 8. R AB = 10. R AC = 9. R AC = 11. R AB = 12. A black box circuit has been measured to give an output voltage versus output current given by the following graph. Compute the equivalent output voltage (V Th ) and resistance (R Th ) of the voltage source model. 13. If Rs = 600 and Vs = 5V, what must the input impedance of a voltmeter be to measure V out to within 1%?...
