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 insulators and history. Insulators are used in all electrical devices from tiny capacitors to giant generators. Engineers need to understand how to design devices with the proper insulator. Unfortunately insulator failure is a primary reason why electrical devices stop working. 1.) Basics 2.) List of Common Insulating Materials 3.) Insulating electric wires
