Questions & Step-by-Step Solutions
What happens to the current in a diode when the reverse voltage exceeds the breakdown voltage?
Step 1: Understand what a diode is. A diode is a component that allows current to flow in one direction only.
Step 2: Know what reverse voltage means. Reverse voltage is when the voltage is applied in the opposite direction to the normal flow.
Step 3: Learn about breakdown voltage. Breakdown voltage is the point at which the diode can no longer block the reverse voltage and starts to conduct.
Step 4: When the reverse voltage exceeds the breakdown voltage, the diode starts to allow current to flow in the reverse direction.
Step 5: This reverse current can increase significantly, which may cause the diode to overheat or get damaged if not controlled.
