Difference between RC filters and LC filters

RC filters LC filters
The RC filter is only useful for small load currents. The LC filters are useful for heavy load currents.
More power dissipated in RC filter. Less power dissipated in LC filter.
It has poor voltage regulation. It has good voltage regulation.
It is cheaper. It is costlier.
It also requires ventilation to conduct away the heat produced in the resistor. It does not require any ventilation because the heat is not produced in the inductor.
It has high ripple factor. It has low ripple factor.
RC is fine for filtering low power signals. LC is fine for filtering high power signals.
