What is an electrical diagram using standard component symbols called?

A schematic.

  1. Schematic ✔
  2. Flow chart
  3. Connection chart

Why: A schematic uses standard symbols, like a zigzag for a resistor, to show how components connect in a circuit.

Huh, didn't know that: A schematic accurately shows component connections, but not wire lengths or what the parts look like.

The dad joke
Why did the schematic never get lost? It always followed the lines.
