3. Capacitor

  1. You’re going to build a circuit with a capacitor. The capacitor can be used to introduce a delay, damping, or store power.
  2. Build the breadboard setup.
  3. Turn on the pump and watch the flag.
  4. Why doesn’t it start flapping straight away?
  1. Now we’re going to build a circuit that can store energy!
  2. Build the breadboard setup.
  3. Keep squeezing the bulb to add pressure to the capacitor.
