which one of the following situations results in a conventional electric current

Question

which one of the following situations results in a conventional electric current that flows northward. A. A beam of electrons moves southward B. A beam of protons moves eastward C. An electric dipole moves southward D. A beam of electrons moves northward E. A beam of protons moves northward which one of the following situations results in a conventional electric current that flows northward. A. A beam of electrons moves southward B. A beam of protons moves eastward C. An electric dipole moves southward D. A beam of electrons moves northward E. A beam of protons moves northward

Explanation / Answer

The conventional direction of electric current is opposite to the direction of motion of electrons

In our question electric current is in the direction northward , so the beam of electrons is moving in sothward

hence option A is correct.

For example consider a batter connected to circuit, the electrons enters into more positive side of battery but current flows from more +ve side .
