Electric spark

Lets say you have a battery and connect wires to each of the terminals. Now you bring both of the wires together to create a spark. Is the spark jumping from positive to negative (current) or from negative to positive (electron flow). Thanks!

Hi, :smile:

Actually, the current flow in metallic conductors is due to free electrons which flow from negative to positive terminal (as electrons are negatively charged particles).

However, spark is electric current thru air, the main constituant of which are positively charged ions which flow from positive to negative terminal under the influence of a potential gradient in air due to the voltage between the battery terminals.
