The electricity charge of the university dormitory is counted by the electricity meter, and finally shared equally with the roommates in the dormitory.

At present, there are many electrical appliances in college dormitory, so each dormitory has independent electricity meter statistics, and the electricity used in the dormitory.

You should try the power consumption. College students can inquire through the campus network during their school days. When you know the electricity consumption of this dormitory and the electricity consumption in the electricity meter is running out, you should charge the card in time. The cost of the prepaid card should be shared equally by several roommates in the dormitory.
