D.C Theory
principles of electricity
- electrons flow from negative to positive
- In conventional current flow current flows from positive to negative
- protons are always in the center of an atom, electrons are outside.
- when a electron joins a atom with protons the electron then becomes a negative ion.
- protons are always in the center of an atom, electrons are outside.
- In conventional current flow current flows from positive to negative
- electrons flow from negative to positive
