Question

An Electric Generator and an Electric Motor How are electric motors related to electric generators? Find the device pictured below, which is a direct-current electric generator. In this case, you provide the mechanical means of rotating the rotor by turning the crank. Plug the wire with dual alligator clips into the end of the electric generator, and attach these clips to a light-emitting diode (LED): hand-operated electric generator LED box 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 current. The end result is an electric motor, such as that used in cooling fans and hard drive motors. b) Hook up a battery to the handheld generator. Is it operating now as an electric generator or as an electric motor? c) Connect the alligator clips from two separate devices and demonstrate they can be used as both a generator and a motor simultaneously.
