What does negative 12 volts mean?
What does negative 12 volts mean? When we say that something has a potential of a specific value (-12 volts in your question), this is RELATIVE to the potential of something taken as a reference-- usually, the earth-- "ground". So-- if we take a 12-volt battery and ground the negative terminal, the positive terminal is at a potential of +12 volts. Is ground negative voltage? If you're working with a single power supply, then your negative voltage terminal is probably the same as "ground". the "ground" terminal is always the zero-volt reference point. If you have a mixed signal circuit,...
