The voltage in the university dormitory is 220 volts. ? Generally, the dormitory is limited to less than one kilowatt, and each school is different. Limit the current by installing an air switch.

Power refers to the amount of work done by an object in unit time, that is, power is a physical quantity that describes the speed of work. The workload is fixed, and the shorter the time, the greater the power value. The formula for finding power is power = work/time. Power is a physical quantity representing working speed. The work done per unit time is called power, which is expressed by P. Therefore, power is equal to the scalar product of the acting force and the speed of the force point of the object.

P stands for power, the unit is "Watt", the abbreviation is "Watt" and the symbol is "W". W stands for work, the unit is "Joule", which is called "coke" for short, and the symbol is "J". "T" means time, the unit is "seconds" and the symbol is "S".

The greater the power, the higher the speed and the higher the maximum speed of the car. Maximum power is often used to describe the dynamic performance of a car. The maximum power is generally expressed in horsepower (PS) or kilowatt (kW), and 1 horsepower is equal to 0.735 kW.

1W= 1J/s, and power is a physical quantity indicating the speed at which an object does work. In physics, power P= work W/ time T, and the unit is Watt W. We often see the units of power in the media, such as k W, ps, hp, bhp, whpmw, etc. And cv used in Italy before.

Here, the kilowatt kW is the international standard unit, 1kW= 1000W, the work required to complete 1000 joules 1 s, and its power is 1kW. In our daily life, we often call power horse power, just as we call torque torsion.

Matters needing attention

According to the relevant provisions of the Property Law, schools have no right to confiscate students' electrical appliances. Because the school charges students accommodation fees at the same time, it is equivalent to signing a lease contract and transferring the right to use dormitory space.

Because for the sake of supervision and safety, the property management can cooperate with the school so that every student who is inspected is present before the search. When providing accommodation for students, schools should clarify the relevant management regulations, indicate the scope of use of electrical appliances, and the authority of school search, and clarify the punishment standards after violations.
