What is the potential in electricity?
Good evening! Tell me, what does it mean when they say that the indicator does not light up at zero because there is no potential on it, what kind of potential ??
Potential is a quantity that characterizes the energy of a charged particle at a specific point in space.
Voltage is the potential difference. Read the course "electricity and magnetism" from any book on physics.
There is no potential at zero, because it is equated to the earth. Those. in this context, we are talking about potential relative to something. Remember that the indicator screwdriver lights up when current flows from phase to ground through your body. FROM GREATER POTENTIAL TO LESS. If zero is grounded (and it is grounded in our electric networks ...), the potentials of zero and earth are close (ideally equal), then the current will not flow and the neon lamp will not burn.
The phrase "fell under the potential" is translated into Russian as "fell under stress."
