Introduction This experiment tests electrical conduction. Electrical conduction is the transportation of an electrical charge through a substance. This is done by the electrical charge/current being sent through the substance via electrons. These electrons carry the electrical current/charge throughout the substance’s length until another conductor is able to receive the electrons charge. Part B: Risk Assessment: During the construction of “the modified hurler‚ “

It is very obvious from the comments posted in this thread that the people driving the use of the RaspberryPi as a PLC training tool have not conducted any professional‚ electrical and electronic engineering research into the design criteria required for an educational PLC or are prepared to acknowledge the legally required European Union safety compliance to IEC61508 and IEC 611313. A PLC’s functional criterion is an industrial control device used to automate electrically driven machinery

Electrical Charges: Electrical charges come as plus or minus. Like charges repel‚ unlike charges attract. Electrons and protons have‚ to fantastic accuracy‚ equal and opposite charges. Quarks have 1/3 the electron charge but are never seen alone! In wires electrons do the moving to carry electrical current. In solutions or plasmas there can be positive charge carriers‚ ions or protons. Although the signal to tell electrons to move in wires travels at about 2/3 the speed of light

I picked up my pencil- this was not an electrical engineering exam at school: instead of lounging at the beach with my friends‚ I had chosen to spend my summer at Specialised Power Systems (“SPS”)‚ designing and building Mr. Rowleys‘s switchboard. As the engineers and I gathered around and started

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

Excel Industries The case “Excel Industries” presents the corporate communication‚ media relations and the daycare for the children of working parents. As a result‚ the child care center‚ operated by Nyloncraft‚ should be closed to solve the problem‚ because it brought bad reputation to the company. Corporate communication is one of the main points in this case. The success and discipline in every business and cooperation depends on liquidation misinformation‚ misunderstandings and
