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.
The basic distinction between the two types is their ability to continue operating under conditions that compromise the integrity of the circuit itself. In a Class B configuration (the more common of the two), outgoing conductors originate at the fire alarm control panel and support peripheral fire alarm devices.
