It takes 6 minutes for a 1.8L electric kettle to boil a full kettle of water. The power is 1300w.220v and 50Hz. How many kilowatts of electricity is needed to boil a kettle of water? How to calculate?
Formula:
Power consumption Q (unit: degree) = power (unit: kW) x time (unit: hour) = 1.3 x 0.1 = 0.13 (degree)
1 kwh = 1000 W · H
Power supply voltage: 220 V, frequency: 50 Hz, rated cooling power: 1100 W, current for cooling
1100/220=5A

The solution is very simple, Sn / P = n, do you have a good idea? I still don't understand the meaning of the problem. If the lamp is connected to the secondary side, it must be connected to the secondary side, as long as the total rated current of the lamp is connected, It's OK to reach the required current of the secondary side, but it's different from the answer. The answer is 5600
