Switches and current

What is a switch's function in a circuit?

• to make the current hotter or colder

• turn on and off the flow of current

• the pathway that current flows

• to add more power to the circuit

Circuit "A" is broken, because:

• the switch is open

• the switch is closed

• the switch is black

• the switch is not there

Will the bulb light up in this circuit? Explain.

• yes, because it has two batteries

• no, because the switch is open

• yes, because it is in a circuit

• no, because the bulb is burned out

In which of these circuits the bulb will light up?

• Circuit C

• Circuit B

• Both B and C

• Circuit A

Who invented the battery?

• Alex Volt

• Alexi Battery

• Alessandro Volta

• Alessandro Battery

Current is...

• how fast the electrons are moving

• the flow of electrical charge

• the power source

• the amount of energy gained/lost across two points

In a Parallel circuit the current is

• the same at every point

• split between the branches

In a Series Circuit the Current...

• is the same at every point

• is shared between the energy users

With what type of circuit should your house be wired?

• series

• parallel

• perpendicular

• dual

The unit for current is

• acceleration

• current

• ampere

• coulomb
