To whom it may concern,
From chemistry I understand that electron flow is from negative to positive, in the external circuit.
I also understand that "conventional current" flows positive to negative, and is used to solve mathamatical electricity problems and it was determined back in the day as current direction. But, if the actual physical flow of current is from neg to pos why do we ground the negative terminal of DC circuits. Wouldn't the electrons go straight into the ground and not return to the positive terminal to complete the circuit. In a car for example the neg terminal is grounded. If DC flows in one direction how can it go from the positive terminal to ground/neg?
Thank you in advance
A ground is defined as a low-impedance electrical connection to earth. Also a common reference point in electronic circuits. We know that electrons flow from negative to positive but we are taking the direction of current from postive to negative. Ok
For the flow of electrons an electric field is required (to exert force on them to move). If we connect the negative terminal to ground, no ...
