Electrical Charges: Electrical charges come as plus or minus. Like charges repel‚ unlike charges attract. Electrons and protons have‚ to fantastic accuracy‚ equal and opposite charges. Quarks have 1/3 the electron charge but are never seen alone! In wires electrons do the moving to carry electrical current. In solutions or plasmas there can be positive charge carriers‚ ions or protons. Although the signal to tell electrons to move in wires travels at about 2/3 the speed of light

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

1. INTRODUCTION Electrical substation for distribution system is the main supply to convert the high voltage (HV) to low voltage (LV) and the place where load are distributed to the consumers. In Malaysia‚ Tenaga Nasional Berhad Distribution (TNBD) used the 33/0.433kV‚ 22/0.433kV‚ 11/0.433kV and 6.6/0.433kV voltage system for the electrical system to supply for domestic consumer and industrial consumer such as factory which will supplied directly from Transmission Main Intakes (PMU)‚ Main Distribution

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

the field is given by the direction of that force. Electric fields contain electrical energy with energy density proportional to the square of the field amplitude. The electric field is to charge as gravitational acceleration is to mass and force density is to volume. 1. Suppose that two point charges‚ each with a charge of +1.00 Coulomb are separated by a distance of 1.00 meter. Determine the magnitude of the electrical force of repulsion between them. Given: Q1 = 1.00 C Q2 = 1.00 C
