institution‚ as I believe that a Masters degree will help me to realize my ultimate goal‚ which is to develop myself as a well educated electrical engineer and promote my existing career in related industries. As a high school student we had an electricity lesson in which we had to make a simple motor using wooden board‚ nails and coated wire and battery. After assembling the materials when I connected the system to the 3 volt battery‚ the rotor‚ made by winded nail‚ started rotating suddenly .it

and escape routes should be established. Regarding electrical safety‚ it is advisable that all electric devices are treated with respect. To this end‚ wiring installation should be checked by approved contractors to ensure that overall system of electricity supply functions properly. To avoid electrical hazards‚ appliances with damaged or worn flexes should not be used; at that wire flexes cannot be used in conjunction. Portable mains-operated appliances should be kept out of the bathroom. Electric

solid was hard. My second activity was called Electrical Static Ball‚ it was a plug in electrical static ball‚ my aim was to get the children to investigate why when they touch the static ball the electricity comes to them and doesn’t hurt them. I also wanted to teach them about the safety side of electricity so all of the children knew how to avoid it. I plugged the static ball into the computer and as soon as it went on the children

Unlike other power plants that rely on coal or other ¬¬¬fossil fuels to create electricity for homes and businesses‚ geothermal power plants use superheated fluids from the earth’s geothermal energy to generate electricity. When magma heats up the water from underground‚ it creates superheated fluids. When these super-heated fluids reach the surface they will be turned into steam. This steam will then power a turbine‚ which will in turn power a conductor. The conductor will then produce electrical

of powder coating begins in the late 1940s and early 1950s‚ where organic polymers were being spray coated in a powder form on metallic bases. Later‚ in 1960 the electrostatic powder coating system was created. This method uses the properties of electricity to apply a high-solids coating to any conductive material. The painting equipment is charged with one electrical polarity‚ while the metal objects to be painted are charged with the reverse polarity. When the coating is sprayed it is attracted to

CHOKE COIL IN TUBE LIGHTS… We saw in the last section that gases don’t conduct electricity in the same way as solids. One major difference between solids and gases is their electrical resistance (the opposition to flowing electricity). In a solid metal conductor such as a wire‚ resistance is a constant at any given temperature‚ controlled by the size of the conductor and the nature of the material. In a gas discharge‚ such as a fluorescent lamp‚ current causes resistance to decrease. This is

Nikola Tesla was a famous inventor‚ electrical and mechanical engineer. George Westinghouse was a famous entrepreneur and engineer who invented the railway air brake and was a pioneer of the electrical industry They were trying to decide which electricity system‚ either direct current (DC) or alternating current (AC)–would become normal. During the War of the Currents‚ Edison was trying to promote the direct-current system (DC)‚ where electrical current would flow progressively in one direction.

When muscles of the body are exposed to electric shock‚ the muscles contract‚ the heart muscle goes into fibrillation electric shock can result in death AC is much more dangerous than DC An electrical shock is experienced when a person become part of an electric circuit. As a result‚ current enters at one point and leaves by another. The severity of the shock is determined by three main factors: The amount of current flowing through the body; The path of the current through the body. The great
