Which of the following accurately describes junction diodes?
a. the negative terminal of the source of voltage is connected to the n-type material within a reverse-biased setup.
b. only a small current will flow through the diode in the forward-biased setup.
c. free electrons are concentrated in the p-type material and holes form in the n-type material.
d. in a forward-biased setup, large numbers of charge carriers will be pulled across the junction and result in a large current.
