1.	Explainthe functionfo thefollowingparts of an electric motor : (i) Armatur . (ii) Brushes . (iii) Split ring .
Answer» Solution :Function of variousparts of an electricmotoris as GIVEN below : (i) Armatur coil CARRIES current . As a result two longarmsof armature coil experience equal FORCE in MUTUALLY oppositedirectionand undertheirinfuencethe coil beginsto rotate . (ii) Brushes drawcurrentfrom split ringsand SUPPLY it to coil. (iii) Split ringsdraw currentfrom the battery . However , split rings changetheir contacts withbrushes afterevery half rotation. As a result current supplied to thearmature coil throught brushes changes its direction afterever half rotation.
