What distinguishes a series circuit from a parallel circuit?

• In a series circuit, components are connected end to end; in a parallel circuit, components are connected alongside each other

• In a series circuit, components share the same voltage; in a parallel circuit, they share the same current

• In a series circuit, components can operate independently; in a parallel circuit, they cannot

• In a series circuit, only one path exists for current flow; in a parallel circuit, multiple paths exist

What is an electric circuit?

• A device that converts electrical energy into light

• A collection of electric cells

• A continuous path for electrons to flow through that powers devices

• Two metals in a chemical solution

What is the primary function of a battery in an electrical circuit?

• To open and close the circuit

• To convert chemical energy to electrical energy

• To increase the flow of electrons

• To provide resistance

What does the term 'voltage' refer to in the context of an electric circuit?

• The rate at which electrons flow through the circuit

• The opposition of current flow

• The device that opens and closes the circuit

• The pressure to push the electrons through the circuit

What is meant by 'current' in electrical terms?

• The pressure to push electrons through a circuit

• The rate at which electrons flow through the circuit

• The device that controls the flow of electrons

• The opposition to electron flow
