Dielectric breakdown of air
Dielectric breakdown of air#
The electric field strength that causes the breakdown of dry air is \(3.00\times 10^6\rm\ V/m\).
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 \(\rm mm\).
Please enter a numeric value.
