Knowledge Check: Electric Circuits/Electromagnetism

A device that transfers energy by providing a path for an electric current is known as what?

• Electric Circuit

• Electromagnetism

• Force Fields

• Magnetic Pathway

Which part of an electric circuit provides the energy for the circuit?

• wire

• light builb

• battery (voltage source)

• switch

What particles flows through an electric circuit?

• proton

• neutron

• electron

• none of the above

Trure or False.

A break in an electric circuit path stops the flow of electrons, preventing the circuit from working.

• True

• False

Which statement is true about the picture?

• The circuit will work because the switch is open.

• The circuit won't work because the switch is open.

• The circuit will work becasue electrons can flow through freely.

• There is no break along this circuit pathway.

What type of circuit is shown?

• series circuit

• parallel circuit

• broken circuit

• force field circuit

What type of circuit is shown?

• series circuit

• parallel circuit

• broken circuit

• force field circuit

If one of the lightbulbs is broken (meaning it won't light) will the other light bulb work?

• Maybe?

• Yes - this is a series circuit. Even though there is a break within the cirucit, electrons can flow freely.

• No - this is a series circuit. The broken lightbulb leaves a break along the circuit not allowing electrons to flow freely, breaking the pathway from the lightbulb to the energy source.

• I do not know.

If I remove the middle light bulb, will the other two light bulbs work?

• maybe?

• Yes - this is a parallel circuit. The other light bulbs still have a direct pathway to the energy source.

• No - you remove one lightbulb and the whole thing doesn't work.

• Yes - this is a series circuit. The other light bulbs still have a direct pathway to the energy source.

A device that uses moving electric charges to produce a magnetic field is known as a/an ____________?

• electric circuit

• electromagnet

• magnetic field

• magnet radiation
