Question

7. Which of the following accurately describes junction diodes? A. In a forward-biased setup, large numbers of charge carriers will be pulled across the junction and result in a large current. B. Free electrons are concentrated in the P-type material and holes form in the N-type material. C. Only a small current will flow through the diode in the forward-biased setup. D. The negative terminal of the source of voltage is connected to the N-type material within a reverse-biased setup.

Answer 1

Answer: A. In a forward-biased setup, large numbers of charge carriers will be pulled across the junction and result in a large current.

Explanation:

A two terminal device which conducts current only in one-direction is known as diode. In forward bias, the p type is connected to the positive terminal and n-type is connected to the negative terminal of the source of the voltage. Thus, in forward bias, large numbers of charge carriers will be pulled across the junction resulting in a large current.

Therefore, correct option is A.
