A capacitor uses air as a dielectric and has a capacitance of 3 UF. A dielectric material is inserted between the plates without changing the spacing, and the capacitance becomes 15 UF. What is the dielectric constant of this material?
A capacitor uses air as a dielectric and has a capacitance of 3 UF. A dielectric material is inserted between the plates without changing the spacing, and the capacitance becomes 15 UF. What is the dielectric constant of this material?
Solution
Co = capacitance of the capacitor with air between the plates= 3 uF
Cm= capacitance of the capacitor with dilectric between the plates= 15 uF
K= dilectric constant=?
K = Cm/ Co
K= 15 / 3 = 5
