Abstract

Methods and systems are described for drilling a wellbore. A method includes: sensing electrical resistance of an insulated conductor extending from a surface of a drill bit to a sensor inside the drill bit; calculating drill bit dimensions based on the sensed electrical resistance; and transmitting sensed electrical resistance, calculated drill bit dimensions, or both uphole to a system for controlling drilling operations.
