a. Suppose a cylindrical wire is 1.00 meters #4 Resistance and Ohm's Law in length with a radius of 0.100 millimeters. If the wire is composed of an alloy of uniform composition with a resistivity of 2.15 x 10-7 2. m, what is the resistance of the wire? b. Suppose three identical wires as described in part (a) Are connected in series. What is the equivalent resistance of this series combination? Suppose a potential difference of 9.00 V is placed across this combination of wires. What current flows through the three wire that have been joined in series? How much power in Watts is dissipated in total in the three wires? c. Suppose three identical wires, again as described in part (a), are connected in parallel. What is the equivalent resistance of this parallel configuration? Again, a 9.00 V potential difference is placed across the combination of wires connected in parallel. How much current flows through each of the three identical wires, and how much current flows through the configuration as a whole? How much power, in total is dissipated in the three wires?
