Voltage

Definition

Voltage is the difference in electrical potential between two points, measured in volts.

Purpose

The purpose of voltage in electrical systems is to drive the flow of electric current. It is a fundamental parameter for designing, operating, and troubleshooting electrical circuits and devices.

Examples of Use

• Household electrical systems typically operate at a voltage of 120V or 240V.
• Electronic devices often require specific voltages to function correctly, such as 5V for USB devices.
• Industrial equipment may operate at higher voltages for heavy-duty applications.

Related Terms

• Current (Amperage): The flow of electric charge through a conductor.
• Resistance: The opposition to the flow of electric current, measured in ohms.
• Power: The rate at which electrical energy is transferred by an electric circuit, measured in watts.

Notes

Understanding voltage is crucial for ensuring the safety and efficiency of electrical systems. Proper insulation, grounding, and circuit protection are essential to manage voltage effectively.
