What’s the difference between negative and ground in circuits?
In: Engineering
Negative is just the opposite side to a power source from positive.
Depending on the context, ground can mean several things. In automotive terms, and many other vehicles, the whole chassis is a conductor. It is used for the negative side to reduce wiring. Only the positive side needs wiring, the negative side is just grounded to the chassis. Some older vehicles do have reverse polarity meaning the positive is ground and negative needs the wiring.
In housing and other real estate there is no positive or negative because it’s alternating current. The ground is a safety device to make sure electricity has a safe path in case of a short or static buildup.
