Electric motor Electric motor, any of a class of devices that convert electrical energy to mechanical energy, usually by employing electromagnetic phenomena. Most electric motors develop their mechanical torque by the interaction of Conductors carrying current in a direction at right angles to a Magnetic Field. The various types of electric motor differ in the … Read more
working principle and use of Generator Generator is a machine that converts mechanical energy into electrical energy. It works based on principle of faraday law of electromagnetic induction. The faradays law states that whenever a conductor is placed in a varying Magnetic Field, EMF is induced and this induced EMF is equal to the rate … Read more
Electric transformers Electrical transformers are machines that transfer electricity from one circuit to another with changing voltage level but no frequency change. Today, they are designed to use AC supply, which means that fluctuation in supply voltage is impacted by the fluctuation in the current. So, an increase in current will bring about … Read more
