It consists of two electric circuits called the primary and secondary and a steel con (which forms a magnetic circuit). The power transformer is an electric machine, without moving parts, for transforming alternating voltage from a higher to a lower voltage or from a lower to a higher voltage. The more torque necessary) for turning the load, the larger is the horsepower rating 5of the motor required for the job. A 16-ft conveyor requires more torque when it is operating at а Ф5 С angle than it does when it is horizontal. Equipment with large, heavy, moving parts require- more torque than equipment with lightweight parts. The amount of counter-torque depends upon the construction of the equipment and upon the amount of opposition added when the machine is performing its job. The opposition is called countertorque or resisting torque. The turning effort that the motor uses to overcome the opposition is called torque. The parts represent an opposition to being moved, and in order for the motor to rotate it has to develop enough force to overcome all opposition to its rotation. Why are these different sizes needed or, in other words, what is different about the various loads that causes one to select one of motor for this application and another for a different application? The answer is obtained by examining the characteristics of the various loads.Īny equipment 4 requiring an electric motor has moving parts. There are many different sizes of electric motors. The electric motor has probably done more to make the farmer's standard of living equal to that of the urban resident than any other electric device including the electric lamp. Electric motors when properly selected and installed serve many years and require only periodic care. Its overload capacity makes it particularly important as a farm power unit since it can develop more than twice its rated power for periods of a few minutes without damage. The electric motor is exceptionally well suited for farm jobs, as it is efficient in converting electric energy into mechanical energy, is easy to start and stop and can be controlled automatically. The amount of energy transfer depends on the intensities the electric and magnetic fields. It should be understood that energy is transmitted only when both electric and magnetic field exist around the сconductor.

The purpose of any circuit is to transfer electric energy from an electric generator battery of alternator 3 to some other point of the circuit, where electric energy is converted to some other form of energy, such as heat, light or mechanical energy. The intensity ofthe electric field per unit potential is a measure of the capacitance 2of the circuit. Electrical flux tubes will extend from one plate to the other. If conductors are connected to metal plates, which are separated by avacuum or insulator, an electric potential will be built between the metal plates. The amount of magnetic linkage (the number of magnetic flux tubes linking the circuit) per unit current is a mea of the inductance of the circuit:ģ. It is not necessary that the circuit be made of segments of equal resistance 1.Ģ. The resistance of the circuit is determined by the properties of the conductor of the circuit. * * Coded by Prasanth K S * * Contact : * /*/ /////////////////////////////////////////////////////////////////////////////// char msg = "WELCOME WIZ" //Change the text here.Parameters of an electric circuit are made up of three circuit components: resistance, inductance and capacitance which determine the circuit characteristics.ġ. * * Comments are given in each statement for editing.
