The potential difference between two points in an electric circuit is the work done when a coulomb of charge passes between the points. You can calculate the size of a potential difference using this equation: V = W Ã· Q. 1  V is the potential difference in volts, V. 2  W is the work done (energy transferred) in joules, J.
Thanks for you help. Yikes, now you got me thinking! I went and my bottle of wilton vanilla and sure enough, it was like I went to the medicine cabinet and opened the bottle of rubbing alcohol! Extract is about 35% or so alcohol, so it may smell like alcohol - but the primary aroma should be vanilla.
