Question

What’s the difference between negative and ground in circuits?

In: Engineering

Answer 1

The terminology is different between Direct Current and Alternating Current. DC circuits have a positive and a negative. AC circuits have a hot and a neutral (for 110v or hot hot on opposite phases for 220v). Both kinds of circuits can have a ground which more often than not eventually end up in the same place as the negative or neutral.
