The house we rent doesn't have any electrical appliances. Every night, we turn on the water heater to take a bath, turn on the light for about an hour, and warm the light in the bathroom for an hour.

This can be calculated. How many watts is the power of the water heater, how long does it last, how many watts is the electric light, how long does it last, and the warm light in the bathroom? (Is it Yuba? How many watts is this and how long will it last?

We know that one degree of electricity is 1000 watts per hour, which means that 1000 watts of electrical appliances need to consume one degree of electricity per hour. The landlord makes clear the respective power of your electrical appliances, then multiplies them by the use time, and then adds them up separately, which is the total power consumption. If someone tampered with it, it's that the meter has been adjusted, or check whether someone else has stolen your circuit. The circuit is easy to check. Follow the wire to find the electric meter. If there is no other wire connection, there will be no problem. Old-fashioned instruments depend on whether the safety of a lead block is damaged or not. That's basically it. I hope to help the landlord.
