Unformatted text preview: Be sure to state the names of the basic principles you would use. What quantities will appear in the equation for the capacitance? How could you test your predicted equation? 3. A coil of wire has a total length of 31.4m. The diameter of the wire itself is 2.00mm. When a 1.00V potential difference is created across the wire, the resulting current is 6.29A. Make an educated guess about the material the wire is made from. Explain your reasoning. 3 4. A Dcell (1.50V emf) battery is connected to a circuit that has a total resistance of 165 Ω . The resulting current is 8.33mA. Find (a)the internal resistance of the battery and (b)the terminal voltage of the battery. 5. A 20.0μF capacitor charged up to 9.00V, is shorted out with a piece of copper wire. The charge on the capacitor is 99% gone after 3.00ms. Find the resistance of the piece of wire....
