Given:

Distance = 1cm

Dielectric constant = 3 × 10⁶ m⁻¹

To find:

Maximum safe potential difference

Solution:

When the conductors are connected, then their maximum safe potential difference applied across conductors will be calculated as -

  VD(max.) = 2 × d × k

here, VD(max.) = maximum potential difference

        d = distance between the conductors

        k = dielectric constant

convert distance into meters,

d = 1cm = 0.01m

k = 3 × 10⁶  m⁻¹

by substituting the values, we get

VD(max.) = 2 × 0.01 × 3 × 10⁶

                = 0.06 × 10⁶ V

So, the maximum potential difference applied across conductors= 6 × 10⁴ V.
