An electric motor is an electric machine that converts electrical energy into mechanical energy. An electric motor uses magnetism and electric current to operate. There are two basic categories of electric motor namely - AC Motor and DC Motor An electric motor is made up of two major parts namely- 1. Rotor - The rotating part of the motor. The shaft is connected to this part for rotation 2. Stator - The stationary part of the motor. The stator can be constructed of permanent magnet or an electromagnet(such as turns of conductor carrying current) The following diagram depict the major type of electric motor we have Magnetism Magnetism field can be derived from two different source such as -           -   Permanent Magnet and          -   Electromagnet Magnetism is the force that creates rotation for a motor  to operate. Recall that a  permanent magnet will attract and hold magnetic mat...

RESISTIVE LOAD vs INDUCTIVE LOAD An electrical load is a device connected to the output of an electrical power source. Example of electrical loads are; DVD, TV, Motor, Charger and any other things or appliance you plugged in to your house hold socket or connect to the mains supply from the distribution company (NEPA). A load is something what removes electrical power from a circuit for some purpose. It can be a lightbulb, a speaker producing sounds, a motor turning some machinery, or an antenna sending radio signals. These electrical loads are however of different type. Types of Electrical Load 1. Resistive load:  It is a type of load that draws current in the same proportion with the apply voltage. They are typically used to convert current into form of energy such as heat. That is the voltage and current are of the same phase. These kind of electrical load converts electrical energy to heat. Example of resistive load include: 1. Electric heater 2. Cooker 3. Incande...

To really understand this concept, we need to know the main type of power we have in an AC circuit which are: -   Active Power or True Power -   Reactive Power and -   Apparent Power -   Active or True Power is the power that is actually been delivered to load I mean the useable power that your generator outputs and its denoted in KiloWatt or Watts. By formula; P=IV or I^2 x R(watts) -   Reactive Power is the power used to establish and maintain the magnetic field also it can be thought of as power that is stored in the generator and released back into the source through AC. By formula; Q = I 2 X Where X is the reactance in Ohms.    Reactive power is basically there due to the presence of inductive or capacitive components in an AC circuit because when current flows through this components some certain amount of power will be dissipated. It can be think of as power due to loss.  -  Apparent ...

Electricity is generated from generation stations such as HEP (Hydro-Electric Power), Solar, Geothermal e.t.c and are interconnected together by the grid system. Generally, electricity used in homes comes from a very far distance and involve a whole lot of process before it finally gets to your home. This process can be classified into 3 main parts which are:  1. Generation  2. Transmission  3. Distribution 1. Generation  It is the root process where electricity is been generated. This generation of electricity comes from various source such as: Hydro-Electricity Power (HEP), Geothermal, Natural Gas, Biodiesel e.t.c. The generation of electricity is usually at a voltage level of 16kV at a frequency of 50Hz and step up by the station transformer to a voltage level of 330kV and because of the fact that its been generated from different location and source there is therefore need of interconnecting all this power station together to a network...
