• Parallel Circuit

• Current Circuit

• Series Circuit

• Conductor Circuit

A path along which electric charges can flow

• Series Circuit

• Parallel Circuit

• Circuit

• Conductor

An incomplete or broken circuit.

• Closed Circuit

• Open Circuit

• Cracked bulb Circuit

Which one will still function if one light bulb goes out?

• A-Series
• B-Parallel
• A-Parallel
• B-Seriese

An electrical circuit is powered by a battery and contains a light bulb producing 1.5 Ohms of resistance. The circuit is flowing at 4 amps of current. What is the voltage of the battery?

• 6.0 volts

• 1.5 volts

• 9.0 volts

• 12.0 volts

The picture shows an electrical circuit. This circuit is a series circuit because: 

• It has 3 light bulbs.
• The same current flows through all three light bulbs.
• It uses a single battery.
• The electrical current is divided between the three light bulbs.

Pick the correct sentence.

• This circuit will work because it is a closed circuit.
• Energy will freely flow in this circuit.
• This circuit will not work because there is no energy source.
• This circuit will not work because there is no switch.

What will happen if one light bulb is removed from this circuit?

• The other bulbs will go out.
• The other bulbs will stay on
• The other bulbs will get dimmer.
• It depends on which bulb they remove.

If I add more light bulbs to a series circuit what happens?

• The current speeds up and the lights get brighter
• The current slows down and the lights dim lower
• The current speeds up and the lights dim lower
• The current slows down and the lights get brighter

Which of the following devices measures current in an electric circuit?

• an ammeter

• an ohmmeter

• a voltage meter

• a resistor
