How may one stop the flow of free electrons in a direct current unshielded wire? Obvious answers like turn off the power or cut the wire will not be responded to!
That will not work in any physics I know.guguma said:If we assume the current is flowing in an infinitely long straight wire, just apply an electric field in the reverse direction of the flow of the current which is sufficient to stop them.
Well yah duh -- that's what I said if you read it.quantaguy said:RANDALLB
All of your physical answers are used now with minimal impact.
Furthermore, this needs to be in quantum physics but someone moved it to classical physics.
So, the question still remains. How does one stop electron flow in a wire attached to a battery through a switch and on the other end an explosive or electronic circuit? When someone presses the switch, the current flows and a bomb goes off.

The purpose of stopping free electron flow in DC unshielded wire is to prevent electrical current from flowing through a circuit. This can be necessary for safety reasons or to control the flow of electricity in a specific direction.
There are several ways to stop free electron flow in DC unshielded wire, including using a switch to interrupt the flow of electricity, adding a resistor to limit the current, or grounding the wire to divert the current to the earth. The method chosen will depend on the specific needs of the circuit.
If free electron flow is not stopped in DC unshielded wire, there is a risk of electric shock, fire, or damage to electronic equipment. This is because the current can flow through unintended paths and cause harm or damage.
No, it is not necessary to stop free electron flow in DC unshielded wire in all circuits. In some cases, the flow of electricity is necessary for the proper functioning of the circuit. However, it is important to carefully consider the risks and needs of the circuit before deciding whether to stop free electron flow.
Yes, there are alternative methods to stopping free electron flow in DC unshielded wire. For example, instead of stopping the flow, a circuit can be designed to control or regulate the flow of electricity using components such as diodes, transistors, or capacitors. These methods can be more complex, but they can also offer more precise control over the flow of electricity.
