A washing machine is rated to consume 500 W of power, and it is plugged into a wall socket that provides an rmsvoltage of 120 V. The 3 m long power cord connecting the refrigerator to the wall socket contains two copper wires,each with a 0.6 mm diameter and resistivity of p = 1.68 \times 10Ⓡ Q-m. What is the total resistance of the powercord in this circuit? (+ 30 points) If the refrigerator is running at full power, how much current will be drawn from the wallsocket? (+10 points) What percent of power supplied by the wall socket will be dissipated in the wires?
