Figure 31 - Resistance Measurements (heat pipe model)
Resistance value between two
heat sinks is sharing resistance
in parallel with anode-cathode
resistance
Resistance value
between heat sink and
test point is snubber
resistance
Snubber Test Point
Resistance between
heat sink and test
point is snubber
resistance
Resistance between
two heat sinks is
sharing resistance in
parallel with anode-
