Q: What is the role of a diode in a circuit?
Solution:
A diode acts as a current rectifier, allowing current to flow in one direction while blocking it in the opposite direction.
Steps: 5
Show Steps
Step 1: Understand that a diode is a small electronic component.
Step 2: Know that diodes have two terminals: an anode (positive side) and a cathode (negative side).
Step 3: Learn that diodes allow electric current to flow easily from the anode to the cathode.
Step 4: Recognize that diodes block current from flowing in the opposite direction, from cathode to anode.
Step 5: Realize that this property makes diodes useful for converting alternating current (AC) to direct current (DC), which is called rectification.
