If the test charge is released, it will be repelled and fly past the starting paint. Its gain in KE at this point is to its decréase Ia PE. At any point, a greater amount of test charge means a greater amount of PE. But not a greater amount of PE per amount of charge. The quantities PE (measured in Joules) and PE/charge (measured In volts) are different concepts. By definition: Electric Potentlal = PE/charge. 1 volt = 1 Joule/1 coulomb. • 1V So 1 C of charge with a PEof 1. J,has an electric potential of 1 V. And 2 Cof : charge with a PE of 2 J has an eleçtric potential of _ _v." If a conductor cannected to the terminal of a battery has an electric potential of 12 V, then each coulomb of charge on the conductor has a PE of. J. You do very little work in rubbing a balloon on your hair to charge it. The PE of several thousand billion electrons (about one-millionth coulomb [10*C] ) transferred may be a thousandth of a Joule (10¬J]. Impressively, however, the electric potential of the ballaon is about Why Is contact with a balloon charged to thousands of valts nat as dangerous as contact with household 110 V?
