Question

The dielectric strength of polyethylene (i.e. the electric field value above which a spark will jump through the material) is about
1.8 × 10 5 V / cm
. The dielectric constant for polyethylene is 2.3. If polyethylene fills the gap between two metal plates 0.20 cm apart, how large a voltage difference can be applied to the two plates before
