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.
Vanilla extract is the most common form of vanilla used today. Mexican, Tahitian, Indonesian and Bourbon vanilla are the main varieties.Bourbon vanilla does not contain bourbon -- it is named for the period when the island of Reunion was ruled by the Bourbon kings of France.Vanilla extract is made by macerating/percolating chopped vanilla beans in ethyl alcohol and water for approximately 48 hours.ourbon vanilla does not contain bourbon -- it is named for the period when the island of Reunion was ruled by the Bourbon kings of France.
