Question

What is the total energy stored between two oppositely charedplaces 1m by 1m in area and 0.01 m apart? The absolute value of thecharge on each plate is 8.85x10^-10 F and the space between theplates is filled with air. The total energy is: A) 1.14x10^-9 J B)1.66x10^-6 J C) 1.10x10^-9 J D) 40.0 J What is the total energy stored between two oppositely charedplaces 1m by 1m in area and 0.01 m apart?

Explanation / Answer

What is thetotal energy stored between two oppositely charged
places 1m by 1m in area and 0.01 m apart? The absolute value of
the charge on each of the plates is 8.85x10^-10 F, and thespace
between the plates is filled with air. The totalenergy is: A) 1.14x10^-9 J B)1.66x10^-6 J C) 1.10x10^-9 J (D) 40.0x10^-11 J

EXPLANATION:
{Capacitance Of Parallel Plate Cap} = C = *A/d =
   = (8.85e-12)*((1.0)*(1.0))/(0.01)
     = 8.85e-10 F
{Energy Stored In Cap} = (1/2)*(Q^2)/C =
     = (1/2)*((8.85e-10)^2)/(8.85e-10)
     = 4.425e-10 J
