ELECTRICAL CONDUCTORS A conductor is an object or type of material which permits the flow of electric charges in one or more directions. For example‚ a wire is an electrical conductor that can carry electricity along its length. Physics All conductors contain electrical charges‚ which will move when an electric potential difference (measured in volts) is applied across separate points on the material. This flow of charge (measured in amperes) is what is meant by electric current. In most

Electrical technology – assignment 4 Properties of electrical materials and Effective use of technology P.5. Describe the properties and a typical application of a solid and a liquid or gas electrical conductor. A conductor is a material that allows free movement of electrons and therefore allows easy flow of electricity. Most conductors are metals. A common metal used as a conductor in electrical technology is aluminium. It is used quite a lot as it cheap‚ lightweight and in abundance compared

Electrical Engineering Work Performed Electrical Engineers research‚ develop‚ design‚ and test electronic components‚ products‚ and systems for commercial‚ industrial‚ medical‚ military‚ and scientific applications (Cosgrove 749). They are concerned with devices that use small amounts of electricity that make up electronic components such as integrated circuits and microprocessors. By applying principles and techniques of electronic engineering they design‚ develop‚ and manufacture products

day‚ Studying electrical engineering technician/technology gives you lots of opportunities of having Variety of career choices. Finishing the three years program at Algonquin college allows you to take many different paths in life. For example‚ you can become an electrical engineering technician which allows you to be a solar energy technician after. On the other hand‚ these two jobs have many differences which make comparing between them possible. First‚ electrical engineering technicians

familiarization of electrical apparatus. Name Image Symbol Uses of functions Galvanometer A galvanometer is a very sensitive meter which is used to measure tiny currents‚ usually 1mA or less. Ammeter An ammeter is used to measure current. Voltmeter A voltmeter is used to measure voltage. Resistor (Fixed and Variable) Fixed Variable A resistor restricts the flow of current‚ for example to limit the current passing through an LED. A resistor is used with a capacitor in

Electrical Cable Cross section is just a two-dimensional view of a slice through an object. An often asked question: How can you convert the diameter of a round wire d to the circle cross section surface or the cross-section area A (slice plane) to the cable diameter d? Resistance varies inversely with the cross-sectional area of a wire. | ------------------------------------------------- Top of Form | Wire diameter d | unit | | | Cross-sectional area A | unit2 | | |
