Each of the plates shown in figure ( 31- E19 ) has serface area `(96/epsilon_0)xx 10 ^(-12) `Fm on one side and the seperation between the consecutive plates is `4.0` mm. The emf of the bettery connected is `10 volts . Find the magnitude of the charge supplied by the bettery to each of the plates connected to it .

Explanation

Here three capacitor are formed and each has area
` A = 96 / eplison_0 xx 10^(-12) F -m`
`d = 4 mm `
`= 3 xx 10^(-3) m `
Capacitance of capacitor
` C = 24 xx 10^(-9) F`
As three capacitors are arranged in series
` C = 8 xx 10^(-9) `
The total charge to a capacitor
` = 8 xx 10^(-9) xx 10 `
`= 8 xx 10^(-8) `
The charge of a single plate
` = 2 xx 8 xx 10^(-8)`
`= 16 xx 10^(-8) = 0.16 mu C` .
