Cartesian sign convection is a way of expressing symbolic equations in a two-dimensional form. It is based on the Cartesian coordinate system and uses positive and negative signs to identify the direction and magnitude of a variable. The sign convection is used to represent equations in a more convenient and visual way, allowing for easier …

safety fuse A safety fuse is a type of fuse that is designed to protect electrical circuits from overloads. It consists of a metal strip or wire that is melted by an electric current, which causes it to open and break the circuit connection. Safety fuses are typically used in circuit breakers, power supplies, and …
A watt-hour meter, or a electricity meter, is a device used to measure the amount of electric energy consumed by an individual or household. The meter records the amount of electrical energy used over time and calculates the cost of the energy based on the rate charged by the energy provider. The watt-hour meter is …
