Answer:
Power = 1920 Watts or 1.92 Kilowatts
Explanation:
Given the following data;
Resistance = 30 Ohms
Voltage = 240 Volts
To find power rating of the kettle;
Mathematically, the power consumption of an electric device is given by the formula;
Power = voltage²/resistance
Substituting into the formula, we have;
Power = 240²/30
Power = 57600/30
Power = 1920 Watts or 1.92 Kilowatts
