A parallel plate capacitor is partially filled with a glass of dielectric constant 4.0, as shown below. The dielectric strengths of air and glass are 30 kV/cm and 300 kV/cm, respectively. The maximum voltage (in kilovolts) which can be applied across the capacitor without any breakdown is (Answer up to two decimal places)
    Correct answer is '18.75'. Can you explain this answer?
    Verified Answer
    A parallel plate capacitor is partially filled with a glass of dielec...
    Given parallel plate capacitor arrangement,
    For the capacitor, we define
    So, equivalent capacitance:
    The electric field density (Dn) will not be affected by dielectric.
    So, it will be same in both the mediums.
    Therefore, we obtain:
    This electric filed density will be same in both the mediums.
    Given, the dielectric strength of two mediums,
    Dielectric strength of air = 30 kV/cm
    Dielectric strength of glass = 300 kV/cm
    So, dielectric breakdown will occur first in air medium.
    Therefore, we obtain the maximum voltage (before breakdown) as:
