I've been asked for a thumbnail model of how the
thermocouple I've superglued to the common lead
of a laser diode to measure its temperature rise is
impacting the measurement.

Obviously, gluing a largish thermocouple to a
small lead is rather like taking a voltage reading
of a high-impedance source with a lower impedance
meter.

This is just a rough estimate, but my
thermodynamics skillset is pretty limited.  Can
anyone give me a clue on how to start?  My first
visit in the meantime is going to be wikipedia-
maybe I can come up with something there.
