Your second question is not infinite current because there is some resistance to the wire. As the wire heats up that resistance also increases.
so I was on the right path but so many sources say you can have voltage with out current. My professor is included as one of the sources.

for the second part, I guess infinite is assuming 0 resistance of copper wire or whatever material. but lets say since the resistance of a thin copper wire is pretty dang small, or current jumps to high amounts.

I=9volts/0.001 ohms. current becomes well, 9000amps at this stage. am I on a correct path?

@ other poster. I am currently reading your post. thanks for the info from both of you guys
