A surgical instrument is disclosed that comprises a motor, a radio frequency (RF) energy generator, a first jaw, a second jaw movable relative to said first jaw in response to an actuation from said motor to capture tissue, and a segmented circuit comprising a first electrode configured to measure tissue impedance at a first position and a second electrode configured to measure tissue impedance at a second position. The RF energy generator is configured to transmit RF energy to the tissue by way of said first electrode or said second electrode. A controller is configured to control said motor based on the measured tissue impedances, energize said first electrode with a first amount of RF energy based on the tissue impedance measured at said first position, and energize said second electrode with a second amount of RF energy based on the tissue impedance measured at said second position.
