Answer / raja

A governor is essentially a speed-sensitive device, designed
to maintain a constant engine speed regardless of load
variation. Since all governors used on diesel engines
control engine speed through the regulation of the quantity
of fuel delivered to the cylinders, these governors may be
classified as speed-regulating governors.

If an electrical component has a positive temperature coefficient, how come such components have high power losses due to heat if current decreases when resistance increases? assuming power given by I^2*R whereby the Resistance is infinite.
