Question

Which of the following statements is true about the flow of electrons in an electric circuit?

• A. Electrons always flow from lower to higher potential
• B. Electrons always flow from higher to lower 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

Answer: (C)

The free electrons experiences electrostatic force in the direction opposite to the direction of electric fired being is of negative charge. The electric field always directed from higher potential to lower potential. Therefore electrostatic force and negative charge or electrons always flows from lower to higher potential until the potantials become equal.
