WebIf an entertainment system draws 217 watts of power when operating, how many kilowatt hours of electricity will it consume in 4 hours of operation? Q2. A \( 20-\mathrm{kW} \) electric heater operates 12 hours per day for 26 days in a month. Determine the electricity bill per month based on a flat-rate tariff of \( 17.1 \phi / \mathrm{kWh} \). Q3. Web1. Estimate of time used: The kettle is used several times per day, for about 1 total hour. 2. Wattage: The wattage is on the label and is listed at 1500 W. 3. Daily energy consumption: (1,500 W × 1) ÷ 1,000 = 1.5 kWh 4. Annual energy consumption: The kettle is used almost every day of the year. 1.5 kWh × 365 = 547.5 kWh 5.
