An autotransformer is an electrical transformer with only one winding. The winding has at least three electrical connection points called taps. The voltage source is applied to two taps and the load is connected to two taps one of which is usually a common connection that is also connected to the source. Each tap corresponds to a different source or load voltage. In an autotransformer a portion of the same winding effectively acts as part of both the primary and secondary winding.
Oh, no... :roll:E-design said:Here is a simple idea from the top of my head. If you know what the VA rating of the transformer is. Lets say it is 60VA. Take a 120Watt 220V filament lamp and put it in series with the transformer. You should drop the excess 110VAC over the lamp. You can confirm this with your meter. The correct way will be to get a 220 to 110 step down transformer. You may see brightness modulation with the lamp method. Hey, your own disco light!
