A coin-operated electricity meter works by allowing the user to insert coins into the meter in exchange for a certain amount of electricity. The meter measures the amount of electricity consumed and deducts the corresponding value from the coins inserted. 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. **

Voltage meter, on the other hand, is a device used to measure the electrical potential difference between two points in a circuit, typically measured in volts. Both current and voltage meters are essential tools for monitoring and troubleshooting electrical circuits to ensure they are functioning properly and safely. **

Pressure is the force per unit area, measured in newtons per square meter (N/m²) or pascals (Pa). It is not measured per cubic meter. Pressure is a scalar quantity that describes the amount of force applied over a given area, not volume. **
