Circuits and Electricity Quiz

What is necessary for a circuit to function properly?

• A broken switch

• An open path

• A closed path

• A single light bulb

What is the role of a conductor in a circuit?

• To block electric current

• To allow electric current to flow with little resistance

• To store electric current

• To convert electric current into light

What happens in a series circuit if one component fails?

• The other components continue to work

• The entire circuit stops working

• The current finds an alternative path

• The voltage increases

In a series circuit, how does the current flow?

• Randomly between components

• In a circular motion

• In a single path, one component after another

• Through multiple paths simultaneously

What is a key characteristic of a parallel circuit?

• It requires no power source

• It allows current to split into multiple paths

• It cannot function if one component fails

• It has only one path for current

How does a parallel circuit differ from a series circuit?

• It has a single path for current

• It is less efficient

• It requires more power sources

• It allows components to function independently

What happens if a light bulb in a parallel circuit is broken?

• The entire circuit stops working

• The other bulbs remain lit

• The current stops flowing

• The voltage drops to zero

What is the main advantage of a parallel circuit over a series circuit?

• It requires fewer components

• It uses less energy

• It allows for independent operation of components

• It is easier to build

In a series circuit, what happens if the switch is open?

• The circuit continues to function

• The voltage doubles

• The circuit stops functioning

• The current increases

What is the effect of a closed switch in a circuit?

• It allows electricity to flow

• It increases resistance

• It stops the flow of electricity

• It reduces the voltage
