1) How much will it cost to run a 1500-watt swimming pool heater continuously for 5 hours if the utility company is charging 10 cent per kWh?
2) Determine the resistance at 20 0c, of 25m of solid aluminum round wire having a radius of 2mm. (Recall the relationship R=pl/A. The resistivity for Aluminum at 20 0c = 2.8 x 10-8 Ωm).
