This counter voltage in the feedback coil causes the transistor to stop conducting and the magnetic to collapse by means of electrical energy from secondary coil. This process helps the transistor to conduct again, repeating the process and creating pulsed dc. The changing magnetic field induces high voltage in the secondary coil. Voltage induced in the secondary coil depends on the ratio of number of turns of Primary and Secondary winding. The distance between the meshes will not let the high voltage arc off on its own. But when mosquito flies in between, it helps in formation of a low resistance pathway, which results in arcing through the body of the mosquito. References Alvin D.
