GLOSSARY

Circuit - A series of electrical components in a closed loop that gives a return path for the electrical current. If the circuit

Conductor

Current

negative pole to the positive creates the current.

Electron - A negatively-charged subatomic particle. They play an important part in electricity, magnetism and

chemistry.

Insulator

Negative - Symbolized with a "-". One of the two "poles" in electronics and magnetism.

Ohm - (Pronounced "oam" A measurement of resistance and used on Resistors (below) to show their rating. The higher

the number, the greater the resistance. Symbolized with a "Ω".

Positive

Volt

Voltage - It creates the current by causing electrons to move in a circuit. Not the same as volt, above.

SYMBOL

A device for storing energy. Batteries have external connectors

(terminals) which connect to the circuit. Electrons move from the

negative terminal (anode) through the circuit to the positive terminal

(cathode). Each symbol represents a single battery.

Light Emitting Diode. These light up when current passes through

only, and the symbol shows which the proper direction.

with a number and "Ω" symbol. The higher the number the greater the

resistance.

A device that uses magnets to convert electrical signal into audible

sound.

A traditional type of switch were a slider is used to open or close a

A spring-loaded switch which will remain open until it is pressed,

allowing the two metal plates to come in contact, closing the circuit.

A small magnetic switch with two metal reeds (wires) inside. When a

magnet comes close to the switch, it will cause the reeds to connect,

A plate with two conductive paths upon it. The two paths do not
