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 | | |

Design of filter circuits for impedance matching of wideband transducers ABSTRACT Wide band piezo-composite transducer is a next generation transducer for under water application. The impedance matching on the interface between electro-acoustical transducer and electrical transmitter has been the most important subject to confirm the high transmitting efficiency. Because the impedance of a wide band transducer depends on signal frequency‚ it is difficult to design a matching network

1. It’s easy to get your first job Electrical engineering students fairly easy find their first job because most employers in electrical field search for fresh mind‚ with fresh knowledge and at the same time they get young people they can mold to their own specific needs and make experts out of them. 2. You can work in another country Working as electrical engineer opens you lots of opportunities in other countries. Laws of math‚ electricity and physics are universal and your gained knowledge
