How can you calculate the generated heat produced by any heating coil by appling 1 kW of electrical energy for one hour?

Answer 1

Applying a power of 1 kW produces an energy of one kilowatt-hour or 3.6 million watt-seconds, equal to 3.6 million Joules or 3.6 MJ.

4.2 Joules is 1 calorie, so divide by 4.2 to convert to calories and the answer is 857 kilocalories. So 857 litres of water could be raised by 1 degree C. Alternatively 85.7 litres would be raised by 10 degrees, etc.

Answer 2

To calculate the heat produced by a heating coil using 1 kW of electrical energy for one hour, you can use the formula: Heat (in joules) = Power (in watts) x Time (in seconds). First, convert 1 kW to watts (1 kW = 1000 W). Then, convert one hour to seconds (1 hour = 3600 seconds). Finally, plug the values into the formula to find the total heat generated.
