possible. The current coil of ammeter has low current carrying capacity whereas the current to be measured may be quite high. For this reason a low resistance is connected in parallel to the current coil. Voltmeters are employed to measure the potential difference across any two points of the circuit these are connected in the parallel to the circuit. The resistance of voltmeter is kept very high by connecting a high resistance in series of the voltmeter with the current coil of the instrument. The

AC Motors vs DC Motors DC Motors Prof. Dr. M. Zahurul Haq zahurul@me.buet.ac.bd http://teacher.buet.ac.bd/zahurul/ Department of Mechanical Engineering Bangladesh University of Engineering & Technology e316.eps ME 475: Mechatronics AC motors are smaller in size‚ reliable and less costly. AC motors run at fixed speed set by the line frequency. Easy speed‚ torque & direction controls in DC motors. DC motors are generally operate at lower voltages which makes these easier to interface with control

which is produced from olive trees in the region. Greek cuisine uses fresh ingredients‚ olive oil‚ and carefully uses herbs and spices. Greek food is recognized for its spit-roasted meats‚ dishes containing olive oil‚ olives‚ chick peas‚ garlic‚ oregano‚ basil‚ nuts‚ and tomatoes. It is also famous throughout the world for their wine. They believe they have the greatest wine because Greece is the birth place of Dionysus. Dionysus is the ancient Greek God of grape harvest‚ winemaking‚ wine‚ ritual

electromagnet consisting of a coil of insulated wire wrapped around an iron core. The strength of magnetic field generated is proportional to the amount of current. Current (I) through a wire produces a magnetic field (B). The field is oriented according to the right-hand grip rule. An electric current flowing in a wire creates a magnetic field around the wire (see drawing below). To concentrate the magnetic field‚ in an electromagnet the wire is wound into a coil with many turns of wire lying side

------------------------------------------------- Electric generator In electricity generation‚ an electric generator is a device that converts mechanical energy to electrical energy. A generator forces electric charge (usually carried by electrons) to flow through an external electrical circuit. It is analogous to a water pump‚ which causes water to flow (but does not create water). The source of mechanical energy may be a reciprocating or turbine steam engine‚ water falling

demonstrated‚ we are providing a DC fan that runs through wireless power. This project is built upon using an electronic circuit which converts AC 230V 50Hz to AC 12V‚ High frequency. The output is fed to a tuned coil forming as primary of an air core transformer. The secondary coil develops a voltage of HF 12volt. Thus the transfer of power is done by the primary(transmitter) to the secondary that is separated with a considerable distance(say 3cm). Therefore the transfer could be seen as the
