Circuits

If each battery has 1.5V then what is the total voltage going to the bulb in parallel?

• 3.0 V

• 0.5 V

• 1.5 V

• 2.0 V

electricity is the flow of what subatomic particle?

• protons

• electrons

• neutrons

• all of the above

Will the light bulb in this circuit light and why/why not?

• 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

What type of circuit is represented by the diagram?

• closed

• series

• open

• parallel

If bulb 1 burns out, what will occur?

• bulbs 2 and 3 will go out

• bulbs 2 and 3 receive more volts

• bulbs 2 and 3 will stay lit

• nothing will happen

The diagram shows a series circuit with three lit bulbs. How many of the bulbs will remain lit if the wire is cut a the point shown by the arrow?

• 0

• 1

• 2

• 3

This circuit has more than one path. When one light goes out, the others stay on.

• closed circuit

• series circuit

• parallel circuit

• open circuit

Which best describes a simple series circuit?

• Electricity flows along one pathway.

• The flow of electricity comes from the switch.

• Electricity flows along many pathways.

• The flow of electricity comes from the light bulb.

What is a circuit with several paths for electricity to flow?

• conductor

• series circuit

• parallel circuit

• open circuit

When you flip a light switch on and off you are closing and opening a circuit.

• true

• false
