DESCRIPTION:The modelling of drops under the action of electric fields is 
 of practical importance in connection with microdevices where small amount
 s of fluid need to be manipulated. Nevertheless\, the associated free boun
 dary problems involve various difficulties: presence of moving contact lin
 es\, changes in the drop's topology\, instabilities of various types\,... 
 Some of these can be overcome by introducing a phase field formulation of 
 the problem. We introduce it in a thermodynamically consistent way and pre
 sent analysis of existence and uniqueness of solutions for the resulting m
 odel as well as numerical implementation for various situations of interes
 t.\n
