PT #1-Problem-Solving with Resistance Part I In a clear short bond paper write your solution on the given problems.

1. What is the resistivity of a material with a resistance of 1052, length of 10m, and cross sectional area of 1x10-6m2? 2. An electrical engineer wants to have a copper wire with resistance equal to 552. If the wire initially has a radius of 1 mm, how long should the engineer cut the wire? 3. What is the resistance of a 50-m long silver wire with a radius of 0.5 mm? 4. A gold rod has a diameter of 20mm and a length of 1 m. Calculate its resistance. 5. A toaster has a heating element made of brass with a length of 2m, an operating temperature of 220 C, and a resistance of 2052. What is the cross sectional area if its operating resistivity is 1.112x 10-682.m?
