Question

What symbol is a diode?

Answer 1

A diode is represented by a symbol that looks like a triangle pointing to a line.

Here’s how it looks:

```

- The triangle represents the **anode** (positive side).
- The line represents the **cathode** (negative side).

The arrow inside the triangle shows the direction of conventional current flow, which is from the anode (positive side) to the cathode (negative side), but current only flows one way through the diode. This is why diodes are often used for controlling the direction of current in a circuit.
