A coin-operated electricity meter works by allowing the user to insert coins into the meter in exchange for a certain amount of electricity.

Once the coins run out, the electricity supply is cut off until more coins are inserted. This type of meter is commonly used in situations where prepayment for electricity is required, such as in rental properties or temporary accommodations. **
