What is the primary property of current in a diode?

The primary property of current in a diode is that it can flow only towards the anode. A diode is a semiconductor device that allows current to pass in one direction while preventing it from flowing in the opposite direction. This directional flow is fundamental to the operation of diodes, which are often used in circuits for rectification, signal modulation, and protection against reverse currents.

When voltage is applied across a diode in the forward direction (positive to the anode and negative to the cathode), the diode becomes conductive, allowing current to flow. However, if the voltage is reversed, the diode becomes non-conductive, blocking the current. This unilateral flow is what enables diodes to control the direction of current in electrical circuits effectively.

Understanding this property is crucial for those working in HVAC systems and related electrical fields, as it influences how various components interact and are integrated into larger systems.
