A. Last Christmas season, Ronnie uses the equivalent of 20 strings of 100 mini-bulbs to light the inside and outside of his home. Each 100-bulb string of lights is rated at 50 Watts. The average daily usage of the strings is 6 hours. The lights are used for approximately 30 days during the holiday season. (a) Determine the resistance of each string of lights. Each is powered by 220-volt outlet. (b) Determine the energy consumed (in kW-hr) by the lights over the course of 30 days. (c) If Ronnie pays 15 pesos/kW-hr for electrical energy, then what is the total cost of Christmas lighting for a single season?
