Current flow through a diode is normally caused by ________.
A)depletion layer breakdown
B)a reverseVoltage across the diode
C)forwardVoltage across the diode
D)thermally produced electron-hole pairs

Question

Quizplus · Accepted Answer

When a forward voltage is applied across a diode, it creates a potential barrier that allows current to flow through the diode in only one direction. This is known as forward biased current flow. In contrast, reverse voltage across the diode would result in very little current flow unless the voltage exceeds the breakdown voltage, which would cause depletion layer breakdown. Thermally produced electron-hole pairs may contribute to current flow in some cases, but this is not the main mechanism for diode operation.
