Further, this measurement may occur in several ways. For example, in some embodiments a physical voltage-measurement system may be placed between the last component in the power delivery system (e.g., a converter, inductor, or capacitor) and the processor. The power from the last component may flow through the system, at which point it is measured. This measurement may then be communicated to the voltage controller. Alternatively, a voltage controller may be connected to several leads that connect to the delivery medium of the power to the processor. For example, the leads may connect to a copper wire embedded within a circuit board. These leads may measure the voltage. Further, because the leads may be directly connected to the voltage controller, the voltage controller may automatically receive the voltage measurement. As another alternative, in some embodiments the electronic device may have the capability to measure and report the voltage of the power it is receiving. In those embodiments, the electronic device may also be configured to deliver the voltage measurement to the voltage controller.
