Question

The potential of two plate of capacitor are +10 V and
-10 V. The charge on one of the plate is 40 C. The
capacitance of the capacitor is
2F
4
F
0.5F
0.25​

Answer 1

Answer:

The capacitance of a set of charged parallel plates is increased by the insertion of a dielectric material. The capacitance is inversely proportional to the electric field between the plates, and the presence of the dielectric reduces the effective electric field.
