There are‚ however‚ four basic types of meter movement that will indicate ac values:- Thermocouple Hot wire Electrodynamometer Iron-vane Electrodynamic ammeters An electrodynamic meter uses an electromagnet instead of the permanent magnet. This instrument can respond to both alternating and direct current and also indicates true RMS for AC. Principle of working The operation

wind as possible. Although we talk about "wind turbines‚" the turbine is only one of the three main parts inside these giant machines. The second part is a gearbox whose gears convert the slow speed of the spinning blades into higher-speed rotary motion—turning the drive shaft quickly enough to power the electricity generator. The generator is the third main part of a turbine and it’s exactly like an enormous‚ scaled-up version of the dynamo (an electric generator‚ especially for direct

impact of the jet on vanes of various shapes like flat plate‚ conical cup and hemispherical cup. Besides that‚ the results from the experiment have to be compared with the theoretical calculations too. 1.0 Introduction Water turbines are widely used throughout the world to generate power. By allowing fluid under pressure to strike the vanes of a turbine wheel‚ mechanical work can be produced. Rotational motion is then produced by the force generated as the jet strikes the vanes. One way of producing

jet engines are combustion engines but non-combusting forms also exist. In common parlance‚ the term jet engine loosely refers to an internal combustion air breathing jet engine (a duct engine). These typically consist of an engine with a rotary (rotating) air compressor powered by a turbine ("Brayton cycle")‚ with the leftover power providing thrust via a propelling nozzle. Jet aircraft use these types of engines for long-distance travel. Early jet aircraft used turbojet engines which were

Example: Drag Machines (or Vanes) You are probably familiar with waterwheels and windmills. Each of these is an example of a drag machine‚ or vane. These machines are used to generate energy using water or wind and have greatly evolved since they were first invented centuries ago. The primary objective when using these machines is to
