Electric field among the two plates

Reference no: EM13680146

1) Two parallel plates are connected to a 40 V battery. The distance among the two plates is 24 cm. What is the magnitude, in V/m, of the electric field among the two plates?

______ V/m

2) Two parallel plates, connected to a 70 V battery, are separated with an air gap. If the plates get close enough, the electric field will exceed the breakdown value of E for air. (A *spark* will occur!) We observe sparking among the plates when the distance is reduced to 18 cm, what is the breakdown value for the air (in V/m)?

______ V/m
