Understanding Electronic Components

Switch

• or closes an electrical circuit

• is a type of resistor

• is a device that stores energy

• is a component that measures current

Transformer

• voltage level in AC circuits

• current level in DC circuits

• resistance in AC circuits

• frequency modulation in radio circuits

Light Emitting Diode (LED)

• emits light when current flows through

• absorbs light when current flows through

• reflects light when current flows through

• blocks light when current flows through

Battery

• stored electrical energy

• mechanical energy source

• chemical energy storage

• thermal energy converter

Resistor

• electric current flow

• voltage drop

• power generation

• signal amplification

Printed Circuit Board (PCB)

• is a type of software

• is used for data storage

• and connects electronic components

• is a type of electronic signal
