Well I guess it's pretty simple, I know E = IR, but I've been thinking of some situations lately that have been confusing me so I decided to ask here. The first one is how does a high voltage stun gun not create high currents? The highest I've seen is 4.5 million volts. I think they simply can't kill you because it is 4.5 million volts rated between the two prongs so the electricity only travels an inch or two correct? My finger reads 7 million Ohms over an inch, which would mean if I stuck that stun gun there it would create .65 Amps right? The second questions is since when you add resistors in series, the total resistance drops, why couldn't you just keep adding resistors until you have an extremely low resistance and create high currents off of low voltages? And how does it make sense that adding more resistors drops overall resistance anyways?
