is there any way to make a step up transformer?
How ever i know this is an old save and you probably aren't going to see this if you are even still on TPT at all.
Spark travels back up the wire after going through the transformer which can stop some spark from going through resulting in a loss in spark.
free to use? with or withought credit?
High-temprature problem refered above, and it's too big.
Constant sparking immediately leaves gaps in electric flow and begins to evaporate water within seconds. Use pure metallic transformers.
