What occurs when the anode is more positive than the cathode?

When the anode is more positive than the cathode, the condition described is known as forward bias. This situation occurs in devices like diodes, where the anode is connected to a higher voltage relative to the cathode. In this state, the barrier for charge carriers is reduced, allowing current to flow easily from the anode to the cathode.

In practical terms, forward bias is essential for the operation of semiconductor devices, as it enables them to conduct electricity more efficiently. When the forward bias condition is met, electrons can move across the junction, facilitating the flow of current and enabling the device to perform its intended function, such as rectifying AC to DC in a diode.

Understanding forward bias is crucial for recognizing how electronic components behave under different voltage conditions and how they can be utilized in circuits.
