A very thin plate of metal is placed exactly in the middle of the two plates of a parallel plate capacitor. What will be the effect on the capacitance of the system?

For a metal `K=oo` and so when `t lt lt d`, the capacitance,
`C=(epsi_(0)A)/(d-t(1-(1)/(K)))=(epsi_(0)A)/(d-t(1-(1)/(oo)))=(epsi_(0)A)/(d-t),` As `t lt lt d, C=(epsi_(0)A)/(d)`
i.e., capacitance will remain unchanged.
