Understanding Circuits Quiz

What is a closed circuit?

• A circuit that is broken and does not allow electricity to flow

• A circuit that allows electricity to flow continuously

• A circuit without a power source

• A circuit that only works at night

What happens if there is a break in a closed circuit?

• Electricity stops flowing

• The light bulb shines brighter

• The circuit works faster

• More electricity is created

Which of these is an example of an open circuit?

• A flashlight that is turned on

• A TV that is working

• A broken wire that does not allow the light bulb to turn on

• A fan that is spinning

In which type of circuit do all components share the same electrical path?

• Parallel circuit

• Series circuit

• Open circuit

• Battery circuit

What happens in a series circuit if one light bulb is removed?

• The other bulbs stay on

• The circuit stops working and all bulbs go off

• The remaining bulbs become brighter

• The electricity moves faster

Which type of circuit allows electricity to take multiple paths?

• Open circuit

• Series circuit

• Parallel circuit

• Closed circuit

Which circuit type is best for wiring lights in a house?

• Series circuit

• Parallel circuit

• Open circuit

• Short circuit

What is needed to complete a closed circuit?

• A switch that is turned off

• A broken wire

• A continuous path for electricity to flow

• A light bulb that is removed

Which of these is a real-life example of a series circuit?

• The lights in a house

• A string of Christmas lights where one broken bulb turns off the whole string

• A city’s power grid

• A mobile phone battery

Why are parallel circuits used in homes?

• So that one broken appliance does not turn off all the others

• Because parallel circuits use less energy

• Because they are easier to build than series circuits

• Because they only work at night
