Question

electric current originates from which part of an atom

Answer 1

nucleus , negatively charged electron and proton positively charged

Answer 2

Answer:  

The electric current originates from the charge of the electrons.

Solution:

The electric current is produced when electron move from one position to another position. The mobility of electrons decide the magnitude of electric current and the number of electrons will decide the resistivity. The charge of electrons is correlated to electric current.

The electric current will be produced in the direction of opposite to the flow of electrons. The drift current is produced in the circuit in the direction of movement of electrons.
