SUMMARY
A 111V electric iron that draws 8.9A of current develops 59,274 joules of heat in one hour. The calculation is based on the formula U = IVt, where U represents energy in joules, I is current in amperes, V is voltage in volts, and t is time in seconds. The discussion highlights a common error in unit conversion, emphasizing the importance of consistent units when performing calculations.
