You have to select the right answer to a question. An electric generator that converts mechanical energy into electrical energy in form. this guide covers electric ac generator questions and answers which include its types and working. 1. What is a Generator? A Generator is a machine which converts Mechanical Energy into Electrical Energy. 2. On which principle a Generator works? The magnetic field used in a generator can be produced by permanent magnets or electromagnets. An armature is the movable coil of wire in a generator that rotates through the magnetic field. A DC generator always has a rotating armature and a stationary field (field windings). A commutator is a ring made of segments that are insulated from one Estimated Reading Time: 3 mins. Answer: In DC motors, Voltage equation is V=Eb-IaRa (V = Terminal voltage, Eb = Back emf in Motor, Ia = Armature current, Ra = Armature resistance).At starting, Eb is zero. Therefore. · Questions on Electric Motors with answers-Q1. WHAT IS ELECTRIC MOTORS? ANS. An electric motor is an electrochemical device that converts electrical energy into mechanical energy. Most electric motors operate through the interaction of Reviews:
