Question

A parallel plate capacitor with oil between the plates (dielectric constant of oil, k = 2) has a capacitance C. If the oil is removed, then the capacitance of the capacitor becomes ______ 

Options

• 2C

• `Csqrt2`

• `c/sqrt2`

• `c/2`

Answer 1

A parallel plate capacitor with oil between the plates (dielectric constant of oil, k = 2) has a capacitance C. If the oil is removed, then the capacitance of the capacitor becomes `underline(c/2)`.
