Answer / bijin

heat sinks are used to enhance the evaporation of
electronic components. if generated heat increases above
the critical level it will damage the component.heat sinks
increases the surface area so that more heat evaporates

Answer / dk

The digital circuit operate on the low power If we are
switching the power level from higher to lower like 230 AC
to 5 DC using 7805 the power is dissipatd in the IC itself
so it get heated and to save the IC from burning we use
heatsinks which dissipate the extra heat

Answer / ragupathi

It obsorbs the heat produced by the digital circuit and
emits it into theenvironment.Thus it saves the digital
circuit from overheating.
