What occurs when the current does not flow in the correct direction through an LED?

When the current does not flow in the correct direction through a light-emitting diode (LED), it will not emit any light. LEDs are designed to operate with current flowing in a specific direction, known as the forward direction, which allows them to emit light as a result of electroluminescence. If the current is reversed or flows in the incorrect direction, the LED enters a non-conducting state. In this state, it effectively behaves like an open circuit and does not produce light. This characteristic is essential for the functioning of LEDs, distinguishing them from other types of diodes that may allow current to flow either way but do not have the same light-emitting properties.
