Calculate the capacitance of a system that stores 4.0 x 10-10 c of charge at 250.0 v.

F

Explanation:

The ability of a capacitor to store an electric charge (Q) per unit of voltage (V) across its plates of a capacitor is called capacitance. SI unit of capacitance is Farad.

It can be measured by using the formula C=Q/V.

Q = 4.0 x 10^-10 C

V = 250.0 V

C = Q / V

   =

   = F

Hence, the capacitance is F.
