Question

Assume Earth and a cloud layer 0.900 Km above the Earth can be treated as plates of a parallel-plate capacitor.
a. If the cloud layer has an area of 2.00 × 104 m2, what is the capacitance?
b. If an electric field strength of 2.0 × 105 N/C causes the air to conduct charge (lightning), what charge can the cloud hold?
c. Describe what must happen to its molecules for air to conduct electricity

Answer 1

Answer:

Consider the Earth and a cloud layer 900 m above the planet to be the plates of a parallel-plate capacitor.

(a) If the cloud layer has an area of 5.0 km2 = 5000000 m2, what is the capacitance? F
