Understanding Closed Circuits & Batteries

Why the circuit must be closed to let the batteries send out electrons? If the circuit is opened, why do the batteries stop sending out electrons?

Because wires must be touching for electricity to flow from one to the other... Is this a serious question?

Closed circuits are essential for the proper functioning of batteries because they allow for a continuous flow of electrons. When a battery is connected to a closed circuit, the chemical reactions inside the battery produce a flow of electrons, which travel through the circuit and power any connected devices.

If the circuit is opened, meaning there is a break in the path of the electrons, the flow of electrons stops. This is because the electrons need a complete path to flow through in order to reach their destination. Without a closed circuit, the electrons have nowhere to go and the chemical reactions inside the battery will eventually come to a halt.

In other words, the circuit must be closed to let the batteries send out electrons because it provides a complete path for the electrons to flow and power the connected devices. Without a closed circuit, the batteries cannot fulfill their purpose of providing a source of electricity.

Additionally, an open circuit can also lead to the buildup of excess electrons in the battery, which can cause it to overheat or even explode. This is why it is important to always properly connect and close circuits when using batteries.

In conclusion, closed circuits are crucial for the proper functioning of batteries because they allow for a continuous flow of electrons and prevent any potential hazards from occurring.
