How to find the area of a parallel plate capacitor
Asked by admin @ in Physics viewed by 275 People
A parallel-plate capacitor has plates of area A. The plates are initially separated by a distance d, but this distance can be varied. The capacitor is connected to a battery.
a) What should the plate separation be if you want to halve the capacitance.
b)What should the plate separation be if you want to halve the capacitance.
c)What should the plate separation be if you want to halve the charge stored?
d) What should the plate separation be if you want to halve the charge stored?
e)What should the plate separation be if you want to halve the energy stored?
f)What should the plate separation be if you want to halve the energy stored?
g)What should the plate separation be if you want to halve the energy density?
