A thin dipole antenna is $$\left( {\lambda /15} \right)$$ long, where $$\lambda $$ is the voperating wavelength. If the dipole has a loss resistance of $$1.5$$ ohm determine its
(i) radiation resistance and
(ii) terminal resistance

In an intrinsic semiconductor the free electron concentration depends on
