##### Reference no: EM13244285

An electric water heater operates at 66 A and 16 kilowatts. The heater is powered by a 240 V power source and contains a hearing element that can be described by N identical 500 ? resistors in parallel. Calculate N (the total number of resistors) and the cost of manufacturing the heating element if in a pack of 100 resistors cost \$0.50.
