Re: Impredance of fluorescents


Can anyone suggest the best (simplest) technique for determining the
impredance of a 20W fluourescent lamp at a specific frequency?

Can it be calculated as an approximation or does it need to be
measured in situ?

At low frequency it is a completely different characteristic.
