1. Dry air will support a maximum electric field strength of about 2.0 x 108 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?

Part B. Let's Solve! Equipotential surfaces and their relation to the electric field
1. Dry air will support a maximum electric field strength of about 2.0 x 108 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?
2. An equipotential surface that surrounds a + 3.0 µC point charge has a radius of 2.0 cm.
What is the potential of this surface?
3. A spark plug in an automobile engine consists of two metal conductors that are separated
by 0.5 mm. When an electric spark jumps between them, the magnitude of the electric
field is 4.0 x 107 V/m. What is the magnitude of the potential difference AV between the
conductors?
