A parallel plate capacitor has a parallel slab of copper inserted between and parallel to the two plates without touching the plates. The capacitor after the introduction of the copper sheet is

A parallel plate capacitor has a parallel sheet of copper inserted between and parallel to the two plates, without touching the plates. The capacity of the capacitor after the introduction of the copper sheet is :

A sheet of copper is inserted in the air gap of a parallel plate capacitor, without touching any of the two plates of the capacitor. The capacitance of the capacitor is

Introduction (parallel plate capacitor)

A parallel plate capacitor is filled by copper plate of thickness b. The new capacity will be

In a parallel plate capacitor of capacitance C , a metal sheet is inserted between the plates, parallel to them. If the thickness of the sheet is half of the separation between the plates. The capacitance will be

In a parallel plate capacitor of capacitance C, a metal sheet is inserted between the plates, parallel to them. The thickness of the sheet is half of the separation between the plates. The capacitance now becomes

The separation between the two plates of a parallel plate capacitor is d. A metal plate of equal area and of thickness (d)/(2) is inserted between the two plates. The ratio of the capacitances after and before this insertion is
