In a circuit diagram, the symbol shown by a long line next to a short line represents
a battery
a filament
a bulb
a wire
Why is an electrical wire covered by plastic?
The plastic is a good conductor of electricity.
The copper wire inside the plastic is a good insulator of electricity.
The plastic will not melt if it gets too hot.
The plastic is a good insulator and keeps the wire from shocking you.
In which of the diagrams below will the bulb NOT light?
In which of these diagrams will the light be the brightest?
What is an insulator?
A circuit in which electric current can flow in an unbroken path
A circuit in which electric current cannot flow
Matter that allows electric current to easily pass through it
Matter that does not allow electric current to easily pass through it
What is an open circuit?
A circuit in which electric current can flow in an unbroken path
A circuit in which electric current cannot flow
Matter that allows electric current to easily pass through it
Matter that does not allow electric current to easily pass through it
What is a closed circuit?
A circuit in which electric current can flow in an unbroken path
A circuit in which electric current cannot flow
Matter that allows electric current to easily pass through it
Matter that does not allow electric current to easily pass through it
What is a conductor?
A circuit in which electric current can flow in an unbroken path
A circuit in which electric current cannot flow
Matter that allows electric current to easily pass through it
Matter that does not allow electric current to easily pass through it
