How can we make a variable capacitor?
How do I calculate the capacitance value?
The capacitance value can be calculated using the equation C = εA/d, where C is the capacitance in farads, ε is the permittivity of the dielectric material, A is the area of the plates in square meters, and d is the distance between the plates in meters. However, the exact value of capacitance may also depend on factors such as plate shape and size, and the dielectric material characteristics.
