Definition of electromagnetic induction and Define Twin Tube light connection with illustration.

Your Answer

Question 1 Eletromagnetic or magnetic induction is the production of an electromotive force across an electrical conductor in a changing magnetic field Question 2 As we know the tube light is a low pressure mercury vapor gas discharge lamp or otherwise called as fluorescent light and mostly produce white light, Now a days CFL and LED lighting products are produced in large scale even though LED lights cannot replace tube lights thoroughly, because the tube light gives smooth bright light, but til now LED  can’t. Here two tube lights are used, in our case each one is 20 watts, each tube light will have two filament with four terminals, connect starter element to any on side of tube light , after that link phase line to the Ballast (choke) through switch. Connect the other terminal of Ballast to terminal of first tube light then connect tube light 2 with first one serially as show in the illustration. Finally bring neutral terminal from tube light 2. http://www.theorycircuit.com/wp-content/uploads/2018/03/double-tube-light-connection-diagram.png
