Dear List, Please settle a minor but bothersome question for me. In an AC powered Tesla tank circuit, what is the peak charge felt by the capacitor? Some on the list say it's 1.4 x VAC, others say it is 2.8 x VAC. This sounds like a "newbie" question, but after reading the mail for many months, it seems that newcomers and old heads alike are not sure about this basic issue. Greg
