Making Sparks Fly?

0 ⤊

You know in science places you see those things that make sparks jump from one thing to another. Am i right in saying that you need high voltage for that rather than high current? or am i complety wrong?

You need high voltage, not high current. Even that little spark that you get from static electricity is a very high voltage but a very low current. You need that voltage to ionize molecules in the air so that current, although small, can flow.

Correct ... it's the voltage that does it.
