What are the basic principles of electricity covered in the NEIEP program?

The basic principles of electricity that are essential for understanding electrical systems, especially in the context of elevators, include voltage, current, resistance, and power.

Voltage refers to the electrical potential difference between two points, which drives the flow of current in a circuit. Current is the flow of electric charge, measured in amperes, and is crucial for understanding how much electricity is being used or supplied in an electrical system. Resistance is a measure of how much a material opposes the flow of current, influencing how much current will flow for a given voltage. Finally, power relates to the rate at which electrical energy is consumed or converted into another form of energy, such as mechanical energy in motors used in elevators.

Together, these principles establish the foundation for analyzing and designing electrical circuits, making them vital for anyone working in the field of elevator technology and basic electrical systems. Understanding these concepts is crucial for ensuring safe and effective maintenance and operation of elevator systems.
