The outer cylinders of two cylindrical capacitors of capacitance `2.2` microFarad each , are kept in contact and the inner cylinders are connected through a wire .A battery of end 10V is connected as shown in figure. Find the totatl charge supplied by the bettery to the inner cylioders.

Explanation

The capacitance of the outer sphere
` C = 2.2 mu F`,
Potential , V = 10 V
Let the charger given to individual cylinder Q
`Q = C xx V `
`= 2.2 xx 10 = 22 mu C`
The total charge given to the inner cylinder
` = 22 + 22 = 44 mu F` .
