MicroVAX II

Regardless if remote sensing is used or not, the power dissipated in the harness will be P=R*I^2, so, proportional to the current squared. With remote sensing I will be a constant as stated, even if the harness resistance goes up, so the power dissipated within the harness then is increased. Without remote sensing I will more than likely go down, but R will still go up in case of an overheated cable or bad connector, provided the bad connector is on the load end and not the source end. But since we are only talking about defective, or inadequate cables, power dissipated in the cable will still be P=R*I^2. Of course all the other equations given by Tony are also correct. Low resistance cables will dissipate the most power in the load and minimum in the cable. Regards - Mike Mike B. Feher, N4FS 89 Arnold Blvd. Howell NJ, 07731 (732) 901-9193
