Shingles is the reactivation of a viral infection in the nerves to the skin that causes pain, burning, or a tingling sensation, along with an itch and blisters in the skin supplied by the affected nerve. It is caused by the varicella zoster virus[1] , or VZVâthe same virus that causes chickenpox.
Types Of Electrical Circuits There are basicly three types of basic electronic circuits a Series Circuit, Parallel Circuit, and Series Parallel Circuit this is a combination of both series and parallel circuits.
Types of Transistors: The photo above depicts an IGBT Transistor from Powerex. 1  Bipolar Transistor-A Bipolar Junction Transistor (BJT) is a three-terminal electronic device made of doped semiconductor material and may be used in amplifying or switching applications.ypes of Transistors-Transistor Applications, Transistor Construction. Transistors are a three terminal semiconductor device used to regulate current, or to amplify an input signal into a greater output signal. Transistors are also used to switch electronic signals.
