Module B Learning Outcomes summary study guide complete and verified 100% Summarize the historical sources of diamond prior to 1867 - -Historically, diamonds were extremely rare and sourced from only a few scattered alluvial (i.e., within river gravels) localities. They were *first discovered in the Golconda Region of India* and then *subsequently in Brazil* by the 18th century. It has been supposed that a maximum 50,000 carats could have been produced annually from India before the 18th...

UNIT- IV TRANSFER ELECTRON DEVICES INTRODUCTION: The application of two-terminal semiconductor devices at microwave frequencies has been increased usage during the past decades. The CW, average, and peak power outputs of these devices at higher microwave frequencies are much larger than those obtainable with the best power transistor. The common characteristic of all active twoterminal solid-state devices is their negative resistance. The real part of their impedance is negative over a ra...

one direction only correct answers A diode is a device that allows current to flow in joining two N-type and P-type semiconductors correct answers PN junction is formed in a single crystal by a two terminal device correct answers PN junction diode is the polarity of the external potential applied to the PN junction diode correct answers The characteristics of diode depends on free of electrons, holes (charge carriers); hence the region is called as depletion region. correct answe...
