A) A solid specimen of dielectric, dielectric constant of 4.5, shown in the figure has an internal void of thickness Imm. The specimen is 1cm thick and is subjected to a voltage of 100 kV(rms). If the void is filled with air and if the breakdown strength of air can be taken as 35 kV(peak)/cm, find the voltage at which an internal discharge can occur. Ilmm 10 mm 100KV (RMS)
