Adielectric material, such as teflon®, is placed between the plates of a parallel-plate capacitor without altering the structure of the capacitor. the charge on the capacitor is held fixed. how is the voltage across the plates of the capacitor affected?

1/ K times

Explanation:

The capacitance of a parallel plate capacitor is given by

Where, A be the area of plates and d be the distance between the plates.

When a dielectric is inserted between the plates, the new capacitance is

The charge remains same.

As we know that

q = C V

The capacitance becomes KC so, to keep the charge remains same the potential difference should be 1 / K times.

V' = V / K

statement #3 on andre"s list is false.
