Intro to Circuits

What do we call this?

• An open switch

• A closed switch

• A voltometer

• A transformer

Does electricity flow if the switch is open or closed?

• Open

• Closed

• Electricity flows through either way

• Electricity can't ever flow through a switch

A moving flow of electrons, much like a moving flow of water, is called what?

• Voltage

• Resistance

• Current

• Battery

Pick the correct answer. The symbols should match the words.

• Current (I)

  Voltage (R)

  Resistance (V)

• Current (C)

  Voltage (V)

  Resistance (R)

• Current (C)

  Voltage (P)

  Resistance (Q)

• Current (I)

  Voltage (V)

  Resistance (R)

Voltage for electricity is similar to water pressure in pipes. What does voltage do?

• Voltage makes electrons flow; it pushes the electricity

• Voltage measures how easily an object lets electrons move

• Voltage measures how many electrons move per second

Resistance in electricity is similar to how big a pipe is in plumbing. What does resistance mean?

• Resistance is how many electrons flow per second.

• Resistance measures how easy it is for electrons to flow through an object.

• Resistance is the push that gets electrons moving.

What does current measure?

• Current measures how many electrons flow per second

• Current is the push that makes electrons move

• Current measures how easy or hard an object lets electrons flow through

• Current measures the total amount of electrons in an object

What supplies voltage (the 'push' that gets electrons flowing)?

SELECT ALL THAT APPLY.

• A battery

• A power source

• A plug in the wall

• A piece of wood

Choose the correct answer. Match the Word to the Unit.

• Current: flovas (f)

  Voltage: vamps (V)

  Resistance: resist (R)

• Current: Amps (A)

  Voltage: Volts (V)

  Resistance: Ohms (Ω)

• Current: Amps (A)

  Voltage: Volts (V)

  Resistance: Ohms (O)

• Current: Amps (A)

  Voltage: force (N)

  Resistance: Ohms (Ω)

Will current flow through this circuit?

• Yes

• No

• Yes if the lightbulb is a small resistance
