    Simple Voltage in Conducting Spherical Shell Question

    When working on homework problems having to do with voltage, there is often the stipulation that V=0 at infinite. If you are dealing with a spherical conductive shell with charge Q, the Electric Field E is equal to K*Q/R^2, where K is the vacuum permittivity constant and R is the radius of the...

    Understanding DC Voltage: Will Touching a 12V Car Battery Cause a Shock?

    Ok, I have a decent understanding of how a potential difference occurs and what I meant to say in my post was touching the positive terminal on the battery and being grounded to the Earth's surface which has a potential difference of about 12v relative to the terminal (right?). But you...

    Understanding DC Voltage: Will Touching a 12V Car Battery Cause a Shock?

    This is probably a very easy question but I have been wondering for a while and can't seem to find a definitive answer anywhere. If you touch one hand to the positive lead on a 12v car battery and are grounded on something not connected to the negative terminal on the same battery, will you...
