Switches.
switch...this break the flow of electricity, from a circuit
An insulator is a material or device that stops or prevents the flow of electricity.
Rubber. Or an insulator.
Battery
Something that does not allow current to flow is called an insulator. "Electricity" doesn't flow, only current, which is one aspect of electricity, does. Note, current is the flow of electrons.
An object that stops the flow of electricity is called an insulator. Insulators prevent the movement of electric charges and are commonly used to protect against electric shocks or to control the flow of electricity in circuits. Examples of insulators include rubber, plastic, and glass.
Something that can't hold electricity is called an insulator, while something that can hold electricity is called a conductor. Insulators prevent the flow of electricity, while conductors allow it to flow freely.
when electricity breaks
A switch in a circuit works by opening or closing a pathway for electricity to flow. When the switch is closed, it completes the circuit and allows electricity to flow through. When the switch is open, it breaks the circuit and stops the flow of electricity. This control of the flow of electricity allows the switch to turn devices on and off in a circuit.
A switch is a device that stops and starts current flow in a circuit.
Resistance. Where as in an electrical circuit there are resistors that restrict the flow of electricity
