    A dielectric placed between the plates of a capacitor

    increases its:
    A Capacitance Correct Answer Incorrect Answer
    B Voltage Correct Answer Incorrect Answer
    C Electric field Correct Answer Incorrect Answer
    D Charge Correct Answer Incorrect Answer

    Solution

    When a dielectric is placed between the plates of a capacitor, it increases the capacitance of the capacitor. The capacitance C with a dielectric is given by: C = ╬║CтВА Where ╬║ is the dielectric constant and CтВА is the original capacitance without the dielectric. Thus, the capacitance increases as the dielectric reduces the electric field inside the capacitor, allowing it to store more charge at the same voltage.
