Question

question 12 of 20 : select the best answer for the question. 12. when an electron is displaced in a semiconductor, the hole thats left behind is a. attracted to the anode of the voltage source. b. considered an impurity in the crystal. c. attracted to the negative terminal of the voltage source. d. incapable of carrying a charge. mark for review (will be highlighted on the review page) << previous question next question >>

Explanation:

• Option A: Anode is positive, holes (positive charge carriers) are attracted to negative terminal, so A is wrong.
• Option B: Holes are not impurities; they are vacancies from electron displacement in semiconductor crystal, so B is wrong.
• Option C: Holes act as positive charge carriers. The negative terminal (cathode) attracts positive charges, so holes are attracted to the negative terminal of the voltage source. This is correct.
• Option D: Holes can carry charge (as positive charge carriers), so D is wrong.

Answer:

C. attracted to the negative terminal of the voltage source.
