Logajan @ Network Systems; 7600 Boone Ave; Brooklyn Park, MN 55428 - You have not taken the internal source resistance into account. When you do, you might find that the *current* is considerably lower. What is the internal resistance of a typical high voltage capacitor that would be used in a "stun gun"? This parameter probably varies with charge, but say a ceramic capacitor is used-- I suspect a very noticable internal resistance, even at full charge. Engineering types -- comments? 73s de VE3WWG
