Parts of a Circuit
100
Aluminium foil - conductor or insulator ?
CONDUCTOR!
100
Name three things that transform electrical energy to energy of motion.
Electric fans, washing machines, merry-go-rounds, conveyer belts, elevators, escalators, mixers...
100
A complete loop through which an electrical current travels.
Closed circuit
100
What kind of circuit is this?
Series
100
What part of a circuit is this object?
Energy source
200
This allows electric current to flow easily though it.
CONDUCTOR
200
The buildup of electrical charges on an object is called...
STATIC ELECTRICITY
200
What happens to the brightness of the light bulbs in a series circuit when you add more lights?
Each bulb gets dimmer
200
Does this diagram represent a series or parallel circuit?
Parallel
200
What part of a circuit is a light bulb?
A resistor (As long as its filament is functional). it changes electrical energy to light and heat energy.
300
Pencil eraser: Conductor or insulator?
INSULATOR!
300
Which type of energy causes friction?
Energy of motion.
300
What happens if there is a break in a series circuit?
Electric current will not flow. Resistors like filaments in lamps will not work.
300
Does this diagram represent a series or parallel circuit?
Parallel Circuit
300
What opens and closes a circuit?
A switch is a conductor that may be used to complete and break a circuit.
400
How are insulators helpful?
They make electrically charged objects safe to handle.
They protect you from electric current and excessive heat.
400
Name three things that use resistors to transform electricity into heat?
Toasters, ovens, light bulbs, dryers, most electric heaters...
400
What will happen (to the flow of electric current) in a parallel circuit if one of its loops is broken?
Electric current will still flow through the unbroken loops.
400
Does this diagram represent a series or parallel circuit?
Series circuit
400
What makes wires valuable parts of a circuit?
They're conductors, allowing electric current to flow, often covered with an insulator to make it safer to touch.
500
What is the definition of an insulator?
Something that electric charges move through with difficulty
500
What can be used to create more energy when we need it?
NOTHING! Energy cannot be created or destroyed!
500
What can cause a break in a series circuit?
Disconnected or broken wires, a switch in the open position, or an insulator placed within the circuit.
500
Does this diagram re
Parallel
500
What's it called when electric current travels along the easiest path, without resistors?
A short circuit. It can be dangerous.
