The dielectric strength of a thermosetting polymer is 35000 V/mm. Calculate the thickness of insulation on a cable working at 28 kV to sustain the breakdown. When the same polymer is inserted in a 9 cm2 parallel plate capacitor with a distance between plates of 0.1 mm, a capacitance of 10–3 μF is noticed. Determine the dielectric constant of the polymer.
