Question

When electric current is passed, electrons move from:

• A. high potential to low potential
• B. low potential to high potential
• C. in the direction of the current
• D. in the direction opposite to the current

Hint:

Always remember:
- Positive charges move from high potential to low potential.
- Negative charges (like electrons) move from low potential to high potential.

Answer 1

The Correct Option is B

Step 1: Recall which way conventional current flows.
By convention, current is taken to flow from the high potential end of a circuit to the low potential end.
Step 2: Remember what actually carries the current inside a wire.
Inside a metal wire it is the free electrons that move, and they carry negative charge, so their motion is opposite to the direction assigned to conventional current.
Step 3: Flip the direction.
Since conventional current goes from high potential to low potential, the actual electrons must be travelling the other way, from low potential to high potential.
Step 4: State the answer.
This is exactly why we say current direction and electron flow direction are opposite to each other.
\[ \boxed{\text{low potential to high potential}} \]
