SUMMARY
The discussion centers on calculating the average current drawn by a typical American household using 800 kWh of electricity per month on a 120 V power line. The correct approach involves converting kWh to watts, where 800 kWh equals 800,000 watts. By dividing this by the total hours in a month (approximately 730.56 hours), the average power consumption is determined to be 1,095 watts. Consequently, the average current is calculated using the formula I = P/V, resulting in an average current of 9.125 A.
