A 250-V Potential Source (A Battery) Is Connected Across the Plates

question 98

Short Answer

A 25.0-V potential source (a battery) is connected across the plates of a $6.66 - \mu \mathrm { F }$ air-filled parallel-plate capacitor having plates that are $1.22 \mathrm {~mm}$ apart. What energy density does it produce between the plates? $\left( \varepsilon _ { 0 } = 8.85 \times 10 ^ { - 12 } \mathrm { C } ^ { 2 } / \mathrm { N } \cdot \mathrm { m } ^ { 2 } \right)$
