What is the function of a diode in a circuit? (2020)

Step 1: Understand that a diode is a small electronic component.
Step 2: Know that diodes are used in electrical circuits.
Step 3: Learn that a diode has two terminals: an anode and a cathode.
Step 4: Recognize that current can flow through a diode only when it is connected correctly (anode to positive, cathode to negative).
Step 5: Remember that if the diode is connected the wrong way, current cannot flow through it.
Step 6: Conclude that a diode acts like a one-way valve for electric current, allowing it to flow in only one direction.
