Q. Consider a dielectrie slap of thickness $1.4\mathrm{cm}$ is placed between the iphere-plane electrodes with thin layer of air (thickness 1.4 aum) in series. The solid dielectrie specimen has a deleciric constant (relative pemittivity) of 3.5 and the breakdown strength of air is $30\mathrm{kV}$ (peaky cm. i) If the applied voluge betwecn the electrades is $10\mathrm{kV}$, find the voltage of the thin layer of air wap. Is it break down explain? b) Find the maximum voltage that can be applied between the electroder without any sperk oceurtence at the air gap. c) If the applicd votiage is $15\mathrm{kV}$, find the masimmin thickness af the air gap without ay ipark oceurtence
