What is the function of voltage in a circuit?

The function of voltage in a circuit is primarily to send electricity. Voltage, often referred to as electric potential difference, is the driving force that pushes electric charges through a conductor. It can be thought of as the pressure that pushes electrons through a circuit, allowing them to flow from one point to another.

When voltage is applied, it creates an electric field that motivates electrons to move, thereby enabling the flow of current. The higher the voltage, the greater the potential for current to flow through the circuit, assuming there is a complete path and resistance in place.

Understanding this concept is crucial as it lays the foundation for how electrical systems operate, influencing the design and troubleshooting of electrical circuits in various applications, including wastewater treatment systems where proper functioning and control of electrical equipment is essential.
