The capacitor
These devices, often small in size, can seem unimportant. But capacitors play a large role in many electrical circuits, and they also pack a punch. Touching a charged capacitor can result in electrocution.
These activities present information and questions on capacitors.
Capacitive circuits
Capacitors are placed in circuits for many reasons. These include controlling the amount and the time that current flows.
These activities present information and questions on capacitive circuits.
