Circuit Review

Why do electrons travel faster in a parallel circuit?

• Becasue they have more energy

• Becasue they lights are pulling on tehm more

• Becasue they have to get full voltage to each light

• Becasue the lights are using less energy

What is current measured in?

• Ω (Ohms)

• V (Volts)

• A (Amps)

• W (Watts)

What is Resistance?

• The flow of electrons

• Electric potential difference

• A battery

• The ability to reduce the flow of electrons

Has your understanding of how circuits increased from our lab activities last week?

• SO MUCH

• I understand them a little better

• I am still confused

• I have no idea

In order for electrons to flow in a path, the switch must be:

• open

• closed

• disconnected

• off

This diagram shows two dry cells connected in:

• series

• parallel

• opposition

Look at the diagram above.....will the light bulb light??

• yes

• no

One advantage of connecting dry cells like this is:

• so that they will last longer

• so that they will provide a higher voltage

• because they look cool

• so electrons have two different paths to follow

This circuit represents:

• 2 dry cells in parallel with a bulb and switch in series

• 2 dry cells in series with a bulb and switch in series

• 2 dry cells in series with a bulb and switch in parallel

• 1 battery with a bulb and switch in parallel

These bulbs are connected in:

• series

• parallel

• opposition

• series, with the dry cells in parallel
