1. A method, comprising:
receiving a first voltage value corresponding to a first voltage at a first side of a connector coupling a source to a load, a second voltage value corresponding to a second voltage at a second side of the connector, and a current value corresponding to current flow from the source to the load through the connector;
determining a first impedance corresponding to the source based on the first voltage value and the current value;
determining a second impedance corresponding to the connector based on the second voltage value and the current value; and
controlling power consumption in a system comprising the load, the source, and the connector, the controlling being based on the first impedance and the second impedance.
