theelectric field
1. Dry air will support a maximum electric field strength of about 2.0 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 fie'1. 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 a distance of 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?
Activity 3: Solving is Fun! Capacitor
1. Calculate the voltage of a battery connected to a parallel plate capacitor
with a plate area of 3.0 cm- and a plate separation of 5mm if the charge
stored on the plates is 6.0 pC.
