Question

When an electric current flows, what is the direction of motion of electrons?

Solution

When an electric current flows, the direction of motion of electrons is opposite to that of the current. For example, in a simple cell of Zn−Cu coupled with dilute sulphuric acid, zinc is the negative pole whereas copper is the positive pole. Current flows from copper to zinc whereas electrons flow from zinc to copper.

Q. Ram learned in high school that electric current is the flow of electrons. Ram’s teacher had also told him that at any temperature the electrons of any metal move very randomly with very high speeds (around 100km/second). So Ram imagines that when a current flows through a conductor, this random motion must cease and all electrons move in one particular direction like a marching army (flow in a sense)
