In microwave and radio-frequency engineering, a stub is a length of transmission line or waveguide that is connected at one end only. The free end of the stub is either left open-circuit or (especially in the case of waveguides) short-circuited. Neglecting transmission line losses, the input impedance of the stub is purely reactive; either capacitive…

Contrary to popular belief, Thomas Edison is often wrongly credited with the invention of electricity. However, it should be noted that while Edison did patent and advocate for direct current (DC) electricity, he was not the actual inventor. In reality, a considerable portion of his achievements were borrowed from other scientific figures, notably the exceptional…

Have you noticed the curving form of a bird’s wing? An airplane’s wing is curved besides. A wing is designed for flight. It has a particular form called an aerofoil. The aerofoil form provides a raising force when air flows around it. Airfoil forms can be found on wings. fans and propellors. Importance:An airplane’s aerofoil…

The given assignment thesis is on the subject “compare/contrast the comparative virtues of air-lift and mechanical fomenters in fermenters ” . In this some cardinal belongingss of air-lift and mechanical fomenters are explained. First, there is a little debut of air-lift fermenter and mechanical fomenters. Second, each belongings is explained with it ‘s similarity and…

Current is produced in a conductor when it is moved through a magnetic field because the magnetic lines of force are applying a force on the free electrons in the conductor and causing them to move. This process of generating current in a conductor by placing the conductor in a changing magnetic field is called…

In its most basic definition. an electric generator is a machine that produces electricity. Generators produce about all of the electricity used by people. They supply the electric power that runs machines in mills. supply illuming. and operate contraptions in the place. There are two chief types of generators – alternating-current ( AC ) generators…

Abstract Electrical cables are the major arteries for electrical power. The power utilities are facing new challenges due to liberalization of electricity. It means reliability demand on distribution network is increasing day by day. The distribution networks are mainly cable networks of different voltage grade and dielectrics. Therefore, the proof design of cables is required…

Introduction This lab was completed to investigate and map the magnetic field pattern of a single straight conductor by comparing it with the earth’s magnetic field. Quantitatively, the purpose of this lab was to determine the horizontal component of the earth’s magnetic field. Magnetic field and electric currents are naturally closely related because anytime a…

What provision must be made for short-circuit conditions in motor circuits? Circuit-breaker or fuse protection of sufficient breaking capacity to deal with any possible short-circuit that may occur must be provided, since overload relays are not designed to operate and clear the circuit in the event of a short-circuit. What are the usual forms of…

VAN DE GRAAFF GENERATOR This is a machine that can build up high voltages of the order of a few million volts. The resulting large electric fields are used to accelerate charged particles (electrons, protons, ions) to high energies needed for experiments to probe the small scale structure of matter. Principle 1. Skin effect 2….
