Question

When an electric current is passed, electrons move from

• A. High potential to low potential
• B. Low potential to high potential
• C. Electrons flow from lower to higher potential except through power sources.
• D. Electrons flow from higher to lower potential, except through power sources.

Answer 1

The correct option is B

Low potential to high potential

Explanation for correct option

(b) Lower potential to higher potential

• Actually higher potential is shown by positive terminal than negative terminal in the battery where the positive terminal has a large number of positive charges and the negative terminal has a lesser number of negative charges.
• When electrons having negative charge pass from low-potential terminals migrate to higher-potential terminals as a result of this.
• Because the flow of conventional current is in the opposite direction as that of electrons. The current is changing its potential state from higher to lower.
• So, this is the correct answer.

Explanation for incorrect options

(a) Higher potential to lower potential

This is the direction of the current, not the electrons, so this is an incorrect one.

(c) Electrons flow from lower to higher potential except through power sources.

The electrons with negative charge pass through lower to higher potential through power sources only not except that.so, it is an incorrect one.

(d) Electrons flow from higher to lower potential, except through power sources.

Here, the direction of the flow of electrons is given wrong. So, this is an incorrect answer.

So, the correct option is (b), Lower to a higher potential.
