A parallel plate capacitor has a plate area of 0.25 m² and a plate separation of 1 cm. If the permittivity of free space is 8.85 x 10⁻¹² F/m, calculate its capacitance.
💡 Hint: Ensure you convert the separation into meters before calculating.
If a dielectric with K = 3 is added to the capacitor described previously, what is the new capacitance?
💡 Hint: Just multiply the original capacitance by the dielectric constant.
