The length of a wire can greatly affect the amount of voltage drop that occurs over its length, meaning that the longer the wire, the more voltage drop you can expect. This is because the wire itself has resistance, and the longer the wire, the more resistance it has.
Additionally, the thickness (or “gauge”) of a wire can also affect its resistance and voltage drop. A thicker wire will have less resistance and less voltage drop over a given length than a thinner wire. So when choosing a wire, it’s important to consider both its length and gauge to ensure that you’re getting the right wire for your needs.
Overall, understanding these factors can help you select the appropriate wire for your specific application, and ensure that it functions properly and safely.
Type and Insulation
