Circuits

When the second bulb is added, they get

• brighter

• dimmer

• broken

• cold

What is the measuring device shown?

• bulb

• cell

• ammeter

• voltmeter

What can you say about the current in the series circuit?

• it splits across the components

• it changes constantly

• it is different in different places

• it is the same everywhere

Which component provides the energy for the charges?

• cell

• bulb

• switch

• ammeter

If the ammeter says the current is 5A, what is the current flowing through one bulb?

• 2.5A

• 10A

• 5A

• 0

If one bulb was broken, what would happen?

• current would no longer flow, so everything would be off

• the ammeter would measure a current from the other bulb

• the switch would keep the current flowing

• the cell would burn out and catch fire

Current is measured in

• Volts

• Watts

• Seconds

• Amps

If the switch was opened, what would happen?

• the ammeter would measure a current flowing

• current would no longer flow, so everything would be off

• the bulbs would stay on because they're connected to the cell

• the bulbs would burn out and catch fire

Name the charged particle, which is part of an atom, that flows in a circuit

• proton

• electron

• neutron

• elepton

If the current flowing through the cell is 2A, what is the ammeter reading?

• 5A

• 1A

• 6A

• 2A
