usually, positive wires have a blue rubber coating, whereas negative wires have a red rubber coating.

One way to tell the difference between positive and negative wires is by their color coding. Positive wires are typically red, orange, or another bright color, while negative wires are usually black or another dark color. You can also use a multimeter to test for voltage: the positive wire should show a higher voltage than the negative wire when tested.
The longer leg of an LED is typically the positive (+) terminal, while the shorter leg is the negative (-) terminal. Additionally, the positive leg usually has a flat edge or a notch near it as a visual indicator.
If the positive and negative wires touch during an electrical circuit connection, it can cause a short circuit. This can lead to a sudden surge of electricity, potentially damaging the circuit components and creating a safety hazard. It is important to ensure that the positive and negative wires do not touch to prevent short circuits.
Electricity moves through a circuit by flowing from the power source, such as a battery or outlet, through the wires and components in the circuit, and back to the power source. This flow of electricity is driven by the voltage difference between the positive and negative terminals of the power source.
Electric current moves through wires or conductive materials in a closed loop circuit, from the positive terminal of the power source to the negative terminal. Electrons carry the negative charge and flow from the negative terminal to the positive terminal.
Electric current is the flow of electric charge through a closed circuit. It is generated by a power source, such as a battery or generator, and flows through conductive materials, like wires, to power electrical devices. The flow of current is driven by the difference in electric potential, or voltage, between the positive and negative terminals of the power source.
