# Dielectric breakdown of air#

The electric field strength that causes the breakdown of dry air is $$3.00\times 10^6\rm\ V/m$$.

## Question Text#

If the potential difference across a pair of parallel conducting plates is 4600 $$\rm\ V$$, at what distance between the plates will breakdown just start to occur? Give your answer in units of $$\rm mm$$.
