Electrical circuit is a path which electrons from a voltage or current source flow. Electric current flows in a closed path called an electric circuit. The point where those electrons enter an electrical circuit is called the "source" of electrons. The point where the electrons leave an electrical circuit is called the "return" or "earth ground". The exit point is called the "return" because electrons always end up at the source when they complete the path of an electrical circuit. The part of an

Electrical technology – assignment 4 Properties of electrical materials and Effective use of technology P.5. Describe the properties and a typical application of a solid and a liquid or gas electrical conductor. A conductor is a material that allows free movement of electrons and therefore allows easy flow of electricity. Most conductors are metals. A common metal used as a conductor in electrical technology is aluminium. It is used quite a lot as it cheap‚ lightweight and in abundance compared

conveniently designed conductive disks allow the electrical load of the generator to be fed either with alternating current or direct current. the loop terminals is sinusoidal with zero mean value (Fig. 2). Its frequency is equal to the number of revolutions per second executed by the loop. Each terminal of the loop is connected to a metallic ring. The contacts with rings are made by means of fixed brushes. If the brushes are connected to an electrical load‚ an alternating current will be established

needs inventory for smooth running of its activities. It serves as a link between production and distribution processes. The investment in inventories constitutes the most significant part of current assets/working capital in most of the undertakings. Thus‚ it is very essential to have proper control and management of inventories. The purpose of inventory management is to ensure availability of materials in sufficient quantity as and when required and also to minimize investment in inventories. Raw
