Understanding the Components
What are the components of an electrical circuit?
Generator, receptor, control elements, and conducting wires
This current flows in one direction and is common in batteries
Direct Current (DC)
This receptor provides light when electric current flows through it.
Bulbs
True or False: Wires connect components and are shown as triangles in diagrams.
False
This component stays open or closed until you press it again.
A switch
Which component supplies the electric current to the circuit?
Generator
Where do homes in Spain get their power?
The electricity grid
This receptor creates sound in a circuit.
Bells
These materials, like copper, allow electricity to pass through easily.
Conducting Materials
pushing this closes the circuit
Normally open (NO) push button
What component connects other components in the circuit?
Wires
This current changes direction repeatedly and is used in homes.
Alternating Current (AC)
This component causes movement when connected to a power source.
Motors
Why is plastic used to cover electrical wires?
to insulate and protect people from electric shocks
pushing this opens the circuit
Normally Closed (NC) Push button
Which component provides light, sound, or movement as the electric current passes through them?
Receptors
Homes in Spain receive a current of ______ Volts
230
This component limits the flow of electric current.
Resistors
These materials, like plastic and wood, do not let electricity pass easily.
Insulating Materials
This switch lets you change the direction of current with one simple move.
