Motors & Generators CtPic Generator and an Electric Motor which is a direct-current of rotating the b ectric motors related to electric generators? Find the device pictured below. electric generator. In this case, you provide the mechanical means e rotor by turning the crank. Plug the wire with dual alligator clips into the generator. h these clips to a light-emitting diode (LED): hand-aparated electric erater LED bex Electric currents created by the magnetic forces present in a generator are indistinguishable from those created by electric forces attributed to a battery -it's all equally viable electric ity. Show that both the handheld electric generator and a 1.5 volt "C" battery can light the LED. Since light-emitting diodes only light up when you run current through them one way (here, from the "red" terminal to the "black" terminal on the LED box), you will have to determine which way to turn the crank on the generator, as well as which way to wire up the battery a) Explain how this generator is working to generate electric currentExplanation / Answer
A generator converts mechanical energy to electrical while a motor convets electrical to mechanical both devices work on the principle of electromagnetic induction i.e voltage is induced by change in magnetic feild.
a) crank is turned for mechanical means of rotating the field (for dc genrator )hence a rotating magnetic feild or flux is created .As the electric generator is based on the principle that whenever a flux is cut by a conductor an emf is induced which will cause the current to flow if the conductor circuit is closed thus the generated current flows in probes which when connect to the led box it glows .
The direction of the induced emf (hence current )is given by flemings right hand rule
