Why do electrons (blue dots) move? The flow of current (+) is opposite to the flow of the electrons. ; note if toward or away from + terminal of the battery. The electrons move due to voltage of the battery

Electrical Machines I Prof. Krishna Vasudevan‚ Prof. G. Sridhara Rao‚ Prof. P. Sasidhara Rao 2 Basic Principles As mentioned earlier the transformer is a static device working on the principle of Faraday’s law of induction. Faraday’s law states that a voltage appears across the terminals of an electric coil when the flux linkages associated with the same changes. This emf is proportional to the rate of change of flux linkages. Putting mathematically‚ e= dψ dt (1) Where‚ e is the induced

power is being wasted as a result of negligence and ineffectiveness on the part of our local power authority (PHCN)‚ State electricity board‚ parastatals in charge of electric power management‚ and various house occupants. It will be observed that large quantity of energy is wasted as a result of poor or manual switching technique of our lighting system in Nigeria. It is a common occurrence and often noticed that the public street lighting along our streets or roads are being left ’ON’ throughout

According to Election Data Services the percentage of electronic voting machines per county doubled between 1998 and 2002 to 16 percent-‚ yet a full replacement of the traditional voting procedure is very unlikely. In its essence‚ an electronic voting machine is a computer assisted self-interviewing device (CASI) giving the voter the opportunity to review and change his/her vote before submitting it. The different types of voting machines allow for different kinds of interaction‚ such as using

Drilling Machine Chapter-4 Drilling machines Any component manufactured has one or more cylindrical hole in them. The process of making a hole is known a drilling. The cutting tool‚ which is used for making holes‚ is known as drill. The drill is a multipoint cutting tool. Definition: Drilling is the operation of making holes in a work piece using a drill bit. The hole is generated by the rotating drill‚ which exerts large force on the work piece clamped rigidly on the machine

Lathe Machine Turning is one of the most common of metal cutting operations. In turning‚ a workpiece is rotated about its axis as single-point cutting tools are fed into it‚ shearing away unwanted material and creating the desired part. Turning can occur on both external and internal surfaces to produce an axially-symmetrical contoured part. Parts ranging from pocket watch components to large diameter marine propeller shafts can be turned on a lathe. The capacity of a lathe is expressed

GRINDING MACHINES Grinding is the process of removing metal by the application of abrasives which are bonded to form a rotating wheel. When the moving abrasive particles contact the workpiece‚ they act as tiny cutting tools‚ each particle cutting a tiny chip from the workpiece. It is a common error to believe that grinding abrasive wheels remove material by a rubbing action; actually‚ the process is as much a cutting action as drilling‚ milling‚ and lathe turning. The grinding machine supports and
