University dormitories limit the total electricity consumption. Generally, the maximum power consumption of university dormitories is1000 W. Some of them are between 800- 1000 W. Every school has different requirements. Because the school dormitory will restrict the use of high-power electrical appliances, the restrictions are relatively low, so high-power hair dryers, induction cookers and the like cannot be used.

The wiring of each dormitory in the university is separate, and the insurance power of a building is far greater than 8000W, which will not explode. Even if it exceeds, it will only block the gate and will not explode. So the average electric power is generally less than1000 w w.

Extended data

Generally speaking, colleges and universities will list high-power electrical appliances (air conditioners, induction cookers, microwave ovens, hair dryers, quick heating, etc. ), illegal electrical appliances (electric blankets, electric cups, rice cookers, electric heaters, etc. ), as well as open flame equipment such as candles, kerosene stoves, alcohol lamps and alcohol stoves, are "forbidden" equipment.

Usually, the most commonly used heating equipment is rapid heating and hair dryer. Their working principle is that current flows through the resistance wire, and the resistance wire heats up to boil water. For the 220V power grid, this load is equivalent to a pure resistor connected to the power grid, and 220V alternating current is added to the resistor. The voltage waveform across the load is in phase with the current waveform flowing through the resistor, that is, the phase difference between them is 0.
