Q8: A solid specimen of dielectric dielectric constant of 4.0, shown in the figure has an internal void of thickness Imm. The specimen is 1cm thick and is subjected to a voltage of 80 kV(rms). If the void is filled with air and if the breakdown strength of air can be taken as 30 kV(peak)/cm, find the voltage at which an internal discharge can occur. 80 KV Iimm 10 mm (ms)
