Directions: Read, understand and analyze each of the problems very carefully. Then, solveand show your complete solutions. Encircle your final answer.1. What is the power consumption of an electric iron if its resistance is 13.1 Q and itoperates on a household circuit with a voltage of 120 V?2. Find the power dissipated in each of these extension cords: (a) an extension cordhaving a 0.0600 n resistance and through which 5.00 A is flowing; (b) a cheaper cordutilizing thinner wire and with a resistance of 0.300 0.3. The diameter of 10-gauge copper wire is 8.252 mm. Find the resistance of a 1.00-km length of such wire used for power transmission.4. What is the resistance of a 20.0-m-long piece of 12-gauge copper wire having a2.053-mm diameter?5. Calculate the resistance of a piece of a 20- gauge copper wire 2 m long. The cross-sectional area of the wire is 0.5176mm

Solution: 1. The expression for the power consumption is p=v2R =120v213.1Ω =1099.2 watt
