1. Check the dormitory announcement or regulations: the school or dormitory management department will post regulations or announcements on electricity consumption in the dormitory.
2. Consult the dormitory administrator or person in charge. The administrator or the person in charge will know the electricity consumption regulations of the dormitory.
3. Check the labels or instructions of electrical appliances. This information usually shows the power or current consumption of the device. Knowing these values, we can estimate the limited electricity in the dormitory.
