Purpose of the Calculator

This calculator can solve for any of the four variables \( C \), \( A \), \( d \), or \( \varepsilon_r \) when you provide the other three. It uses the following rearranged formulas to solve for each missing variable.

• To solve for \( C \) (capacitance): \[ C = \frac{\varepsilon_0 \varepsilon_r A}{d} \]
• To solve for \( A \) (area): \[ A = \frac{C \cdot d}{\varepsilon_0 \varepsilon_r} \]
• To solve for \( d \) (distance): \[ d = \frac{\varepsilon_0 \varepsilon_r A}{C} \]
• To solve for \( \varepsilon_r \) (relative dielectric constant): \[ \varepsilon_r = \frac{C \cdot d}{A \cdot \varepsilon_0} \]
