Original poster: "by way of Terry Fritz <twftesla-at-qwest-dot-net>" <Esondrmn-at-aol-dot-com> Any advice on how to measure the output current of my new 4 kv 20 ma transformer? I do not have an AC milliamp meter. How about placing a 2,500 ohm resistor across the output. If I have 20 ma, I should measure 50 volts ac. Sound ok? Thanks, Ed Sonderman
