Circuit diagrams (symbols)

Scientists draw circuits with symbols instead of pictures:

  • Cell — long + short parallel lines (+ and −)
  • Battery — multiple cells in series
  • Wire — straight line
  • Switch — angled break in the line
  • Bulb — circle with a cross inside

Circuit diagrams are cleaner than pictures and universally understood.

Example
Instead of drawing a cell with body and label, you just draw |‖ and the meaning is clear.
