Bipolar junction Transistors 1. Introduction The Bipolar Junction Transistor (BJT) is one of the most important solid-state devices. It is a two-junction‚ three-terminal device‚ in which the current flow properties of one p-n junction can be modulated by another p-n junction. The structure can be either p-n-p or n-p-n. The three terminals are called emitter‚ base and collector. The circuit symbols of the two types of BJT are shown in Fig.1. The arrow on the emitter signifies the direction of

LIGHT EMITTING DIODES Light Emitting Diodes are electronic components that use the flow of electrons to excite materials into emitting photons of light. A diode is a basic electronic component that allows electricity to flow one way only. The discovery of "light emitting" diodes we believe was an accident sometime around 1907 when a diode in an early radio transmitter was noticed to glow when in use. Incandescent bulbs use resistance in a filament to impede the flow of electricity‚ heating

Tax Problem 2-67 Larry has severe vision problems and has previously claimed the additional standard deduction available to blind taxpayers. This year‚ Larry was prescribed a new type of lens that vastly improved his vision. However‚ he began to suffer severe pain‚ infection‚ and ulcers from the lens‚ and had to remove the lens. The doctor said he could continue to wear the contact lens‚ but only for short time periods. The issue is if Larry is able to claim the additional standard deduction to

Is rationalization a desirable strategy for managing and organizing Junction Hotel in the current economic climate? Discuss your answer with reference to the topic of organisational change. Rationalization is an organisational concept that aims to increase a firm’s productivity‚ as it grows in size‚ through a reorganisation of its current system of operations. Throughout this essay I will be referring to the Junction Hotel case study along with other articles and critiques of the rationalization

Exocytosis and the Neuromuscular Junction: How Does Botox Work? Exocytosis is the process in which secretory vesicles are exported out of the cell membrane. These vesicles contain proteins which are then transported to parts outside the cell (Wilfred D. Stein‚ 2012). Neurotransmitters are released during this process into the synaptic cleft. These transmitters attract other transmitters to muscle membrane infoldings‚ which are called junction folds (Etherington & Hong‚ 2011). They diffuse across
