For somewhat reason direction of the electric current denoted by dot and cross in this video is in wrong, or it is marked for electrons, not for positive charged particles, as it should be.

*as it shouldn't be, but is.

[@anshraj397]

Bro current moves from negative ions to positive ions...i.e electrons to protons...
