1. What is the resistance of a 22 AWG copper wire that is 5" in length? 22 AWG has a diameter of 0.02535" 1" = 0.0254m Resistivity of Copper = 1.72x10-8 ohm-m 2. 3. What is the resistance of a copper bar that is 0.25" x 0.75" x 120"? If a copper wire has a resistance of 10ohms at 20C, what is the resistance at OC? Temp Coefficient of copper = 0.00393 4. If a copper wire has a resistance of 10 ohms at 20C, at what temperature would the resistance be 12.5 ohms? 5. In Circuit 1, determine the voltage drop across each resistor. 6. In Circuit 2, determine the total resistance, the current, the voltage across each resistor, the power supplied by V1, and the power dissipated by each resistor.
