Answer / rohit kumar soni
VARIAC, AUTO TRANSFORMER, DIMMERSTATE ALL DEVICE WHICH CAN
BE USED TO GET VARIABLE AC VOLTAGE AT THE CONDITION OF NO
CHANGE IN INPUT AC VOLTAGE.THIS TYPE OF TRANSFORMER IS
CALLED AUTO TRANSFORMER. IN THIS TRANFORMER THERE IS A COIL
WINDING CONNECTED TO AC INPUT AND ONE OUT PUT CONNECTION IS
COMMAN LINE AND ANOTHER OUTPUT LINE MOVES WITH THE HELP OF
A CORBAN SLIDER ON THE AC INPUT COIL AS SLIDER MOVES WE GET
VARIABLE AC VOLTAGE .

Answer / s.h.bhopatkar
All products are exactly one and the same. "Dimmerstat" is
originally registered by "AE" the pioneers in this product
in India.All other manufactures have registered this product
in different names,like "Varivolt""Varitrans" etc.
The basic product is a Toroidal Transformer,with a moving
brush to short only 2 turns at atime.The coil is generally
wound for Single phase voltage,generally 230V.3 such coils
are assembled on a common shaft,which can either moved
manually or thro a stepped motor for remote operation

Answer / chandra sekhar
A transformer, in which only one winding is there is called so, a part of the winding is common to both the primary and secondary circuits, it is called autotransformer/variac/dimmerstat. ["Variac" and "Dimmerstat" are trade names of variable autotransformers. "Dimmerstat" is originally registered by "AE" the pioneers in this product in India.All other manufactures have registered this product in different names,like "Varivolt""Varitrans" etc.]
(Dimmer is: A rheostat that varies the current through an electric light in order to control the level of illumination)
The "auto" (greek for "self") prefix refers to the single coil acting on itself (it doesn.t signify any kind of automatic mechanism).

Answer / bhaskar 222
DIMMER STAT IS A VARIABLE VOTAGE DEVICE BY GIVING TAPPING
CONNECTION TO THE WINDING WE GET THE REQUIRED VOTAGE.THE
STARTING OR ENDING TAKEN AS COMMON
* VARIAC IS A VARIABLE AC VOLTAGE DEVICE
* AUTO TRANSFORMER IS A FIXED INPUT AND OUTPUT TAKEN BY
GIVING TAPPING
