Instruction: Calculate the electric field in the region given a mathematical function describing its potential in a region of space. 1. Dry air can support a maximum electric field strength of about 4.5 x 10 V/m. Above that value, the field creates enough ionization in the air to make the air a conductor. This allows a discharge or spark that reduces the field. What, then, is the maximum voltage between two parallel conducting plates separated by 3.5 cm of dry air?
