Basic Electronics Components

Mikayla Denny

Function: Stores electrical energy. Has polarity (positive and negative terminal)

Battery

Function: Amplifies voltage or current. Has three terminals.

BipolarTransistor

Function: Slide or button that opens or closes a current. May have many terminals, but needs at least two.

Switch

Function: Resists flow of current.Resistor

Function: Variable-value resistor; adjusts resistance by twisting shaft

Potentiometer

Function: Special resistor varying resistance according to the intensity of the light hitting the surface.

Photocell

Function: Temporary battery; stores small amounts of electricity.

CeramicCapacitor

Function: Stores large amounts of electricity; has polarity.

ElectrolyticCapacitor

Function: Allows current to flow through in a single direction. Has two leads.

Diode

Function: Emits light when a current flows through. Has two terminals.

Light Emitting Diode

Function: Allows current to flow only after a positive voltage is applied for a moment to the gate.
