HV Spark

© http://EduMation.org
A demonstration on the generation of a high voltage spark by a step-up transformer having a 500-turn primary and 23000-turn secondary. The applied voltage is 300V and the generated voltage is ideally 23000/500 x 300V =13.8 kV but it is less practically. Demonstrated by Mustafa Daif with the assistance of Ali Taha and Yosri Idrees.

Hi can you tell me the purpose of the steel core in a step up transformer?

[msdaif]

The purpose is to obtain high flux produced by minimum energy (current). Without the steel core, we would need higher current to produce the same flux. The steel core collects the magnetic flux instead of being wsted in air, although some portion of the flux is lost in the air.

Ah thanks, will any type of steel work?

[msdaif]

Yes but the current value differs depending on a factor known as permeability of the material

[user12119]

Would an iron nail work?

[msdaif]

Yes.

@edumation wow i was right NICE ! thanks man and how would i do how many watts ? Like if i wind it with 12G wire i would get 20 amp in and 20 amp out ?

[edumation]

@67tr876 Yes.

Hi. I want to make my own step up but i need 120 volt up to 180 volt would i do 120 turns for 120 in and then 180 turns for 180 out ?
