I believe that two of the items in the fine review by Spies and Trohman need to be corrected: Current (in amperes) is the FLOW (or flow rate) not the AMOUNT of electrons. The unit of quantity or amount of electrons (or electric charge) is the Coulomb, a unit rarely seen by physicians. Thus, a Coulomb is the amount of electric charge as a result of a current of 1 ampere flowing for 1 second. Although DC can be used for power transmission (particularly at extremely high voltage), most of the power transmission lines in the USA are AC, not DC. Conflict of Interest:None declared |
