A switch, switching transistor, or circuit breaker usually does.
The switch.
A switch.
Generally a circuit breaker (like a light switch) But I guess you could use a resistor of the right resistance If you are talking about the circuit breaker there is an electromagnetic coil in it which get magnetized on a specific amount of current and breaks the circuit

Inside an electric cell, chemical energy is converted into electrical energy. When the cell is part of a complete electric circuit, the electrical energy is then converted into other forms of energy, such as light, heat, or mechanical work, depending on the components in the circuit.

Battery.
A part of a fence that opens and closes is called a gate. Gates provide access through the fence while maintaining the boundary it establishes. They can come in various styles and materials, depending on the design of the fence and the intended use.
Current is the flow of electric charge or the rate of the flow of an electric charge through a conductor.
