The power to operate a heater comes from a 24-volt [V] power supply. The efficiency of the heater is 73%, and the heater produces 700 kilojoules of output heat per hour [kJ/h]. Determine the resistance of the heating element in units of ohms [Ω].
Answers: 2
), measured in watts, is represented by:
(Eq. 1)
- Heating efficiency, dimensionless. 
- Power supply voltage, measured in volts. 
- Heater resistance, measured in ohms. 
, 
and 
, then the heater resistance is:
