When the heater is not connected, the voltage is 210v. When the heater is connected, the voltage drops to 200V? In winter, after Li Ming plugged in the electric heater, he found that the light in the room was dim. He used a voltmeter to measure the power supply voltage. The result showed that the voltage was 210v when the heater was not connected. The voltage dropped to 200V when the heater was connected. The electric heater he used was marked with "220V, 1000W". From this, we can know the resistance of the power supply circuit__________ Ω, the actual power of the electric heater is____________ W. It's the resistance of the power supply circuit, not the resistance of the heater. 2.54 Ω, 826.4 w

The resistance is 220 ^ 2 / 1000 = 48.4 ohm
The actual power is 200 ^ 2 / (242 / 5) = 826.4 watts

An electric heater is marked with the words "220 V, 2000 W". If the voltage applied to both ends of the electric heater is 220 V, then the power of the electric heater is 220 v_______ W (regardless of the effect of temperature on the resistance, keep the integer number)

2000w
