Parts of the Circuit Board
Need basic information about circuits? The Electrical Circuit
MatchCard from the Light & Energy Unit study introduces students to the concept of an electrical circuit. An electrical circuit is made on a circuit board with additional electronic devices to process and change the incoming signals.
Electronic Inputs & Outputs
are taught in the Technology MatchCard #3.
The cell supplies the energy for the circuit. A battery or electrical energy can be used to run your circuit board.
The transformer is comprised of two or more coils which increase or decrease incoming voltage.
The resistor decreases the current going through the circuit. Otherwise it becomes hot from wasted heat.
Capacitors are metal plates connected to one of two wires that store electrical charges until they reach a certain level.
Amplifiers turn weak electronic signals into strong electronic signals able to do more work.
A small amplifier that decreases the size of the machine since it amplifies many times its own size
Building Circuit Boards
Our favorite kit is Snap Circuits.
Snap Circuits have colorful, easy-to-handle, kid-friendly kits. Their color coded instruction manual is simple for a kid and non-techie adult to follow.
