if they're not then the circuit will not work and it won't be able to power wat u want it to power for example a lightbulb.it will be an open circuit
They can, but not required.

Electric circuits can be described as closed loops that allow electric current to flow, enabling the operation of various electrical devices. They consist of components such as resistors, capacitors, and power sources, which work together to control and manage the flow of electricity. Understanding electric circuits is essential for designing and troubleshooting electrical systems.
Advantages in electric circuits : Advantages of using the rheostat in electric circuits is optional as you could just use the dial on the power-supply to vary the voltage (p.d.), and therefore the current. The advantage of using the rheostat is that you can control it to give you nice even numbers for the voltage.
Water pipes represent electric circuits as both systems involve the flow of a substance—water in pipes and electric current in wires. Just as water pressure drives the flow through pipes, voltage pushes electric current through a circuit. Valves in water pipes can be compared to resistors or switches in electrical circuits, controlling the flow of water or electricity. Additionally, blockages in pipes can represent short circuits or faults in an electrical system, disrupting the flow.
Open circuits and closed circuits both allow the movement of electric energy. In an open circuit, electric energy cannot flow because the circuit is incomplete. In a closed circuit, electric energy can flow because the circuit is complete and forms a continuous pathway for the energy to move.
