The present disclosure relates to a sensing system that includes a plurality of resistive elements coupled to a plurality of nodes and a controller configured to index through a plurality of modes to measure an electrical characteristic for each resistive element. Each mode of the plurality of modes represents a different combination of power, return, or open circuit condition applied to each of the plurality of nodes. The controller is configured to calculate, for each of the modes, a total power consumed by the system and a power consumed by each of the resistive elements based on the measured electrical characteristics, to determine a physical parameter.
