# How Much Energy is Stored by the Electric Field Between Two Square Plates?

What is the formula to calculate the energy stored by the electric field between two square plates?

The energy stored by the electric field between two square plates can be calculated using the formula Energy = (1/2) * capacitance * voltage^2.

## Explanation:

**The energy stored by the electric field between two square plates can be calculated using the formula:**Energy = (1/2) * capacitance * voltage^2 To find the energy, we first need to calculate the capacitance of the plates. The capacitance can be calculated using the formula: Capacitance = (permitivity of free space * area) / distance In this case, the area of each plate is (9.3 cm)^2 and the distance between the plates is 2.3 mm. The permitivity of free space is a constant. After finding the capacitance, we can then calculate the energy by substituting the values into the first formula given above.
