Two parallel plates are connected to a 120-V DC power supply and separated by an air gap. The largest electric field in air is 3.0 x 106 N/C. (When this “breakdown value” is exceeded, charge is transferred between the plates, reducing the separated charge and the field through sparks or arcing.) Calculate the smallest possible gap between the plates.
