In the context of electricity, "voltage" refers to the pressure behind the electrical current. It is a measure of the electric potential difference between two points in a circuit. This potential difference is what drives the flow of electric current through a conductor, such as a wire. Voltage can be thought of as the force that pushes electrical charges to move, enabling electrical energy to be transferred and utilized in devices.

Understanding voltage is essential for home inspectors, as different systems and appliances operate at various voltage levels. This knowledge helps assess whether the electrical systems in a home are functioning safely and effectively, as well as ensuring that any modifications or installations will be compatible with existing infrastructure. By recognizing voltage as the driving force behind electrical current, inspectors can better evaluate the safety and efficiency of a home's electrical system.
