Abstract: An example provides an apparatus for determining an attribute of an adapter based on a ratio of voltage divider outputs. The apparatus may include a first analog-to-digital converter to provide a first digital signal corresponding to a first output voltage of a first voltage divider connected between a power node and a ground node, the first voltage divider formed, at least in part, when the apparatus is operatively coupled to the adapter. The apparatus may include a second analog-to-digital converter to provide a second digital signal corresponding to a second output voltage of a second voltage divider connected between the power node and the ground node. The attribute of the adapter may be determined based on a ratio of the output voltages.
