Readings at nodes for the above Figures. For figures 1 and 2 the resistance was measured with a DMM. In figure 3 the voltages were measured at the labeled nodes with respect to ground. 1. a. 0.999k b. 0.999k c. 2.036k d. 1.992k e. 4.011k f. 10.774k g. 498 h. 0.7508k i. 0.9072 2. 3a. 1. 0.06 2. 0.499k 3. 0.06 3b. 1. 0.06 2. 0.749k 3. 0.997k 4. 0.748k 5. 0.06 3. 4a. 1. +11.855 V 2. +5.913 V 3. +0.05 mV 4b. 1. +11.935 V 2. + 8.94 V 3. +5.962 V 4. +2.985 V 5. +0.06 V 4c. 1. +11.897 V 2. +8.938 V 3. +0.05 mV How did the experimental results match the theoretical expectations? - The resulting resistances and voltages were very close to the theoretical expectations considering the 5% tolerances for the resistors.

Unformatted text preview: How accurate were your results?-Our results, most of them, were carried out to the third decimal place, I doubt that the meter is very accurate past the hundredths of any unit. Italicized questions from the lab manual. What would be the resistance to ground at the central tap?- 5k What would be the resistance to ground at tap number 2?- 1k||9k Assignment Thevenin at 1. 2k; 12V 2. 1||1 = 0.5k; 6V 3. 0k; 0V Thevenin at 1. 4k; 12V 2. 3k||1k; 9V 3. 2k||2k; 6V 4. 3k||1k; 3V 5. 0k; 0V Thevenin at 1. 4k;12V 2. 1||3k; 9V 3. 0k; 0V Use fig.4 and Ohms Law to find what currents would flow to ground. Fig 4a. 6mA 4b. 3mA 4c. 3mA What assumption is implicit regarding the internal impedance of the voltage source?- 0.0 ohms How do your answers compare?- Very close to expected....
