A capacitor is made with nine plates separated by sheets of glass having a thickness of 0.21mm and a relative permittivity Of 9.48. The area of one side of each plate is 620cm^2. A potential difference of 480V is maintained across the terminals of the capacitor. Calculate the charge on the capacitor.

Solution

we know that charge (Q) =CV

V=480 Volts

thickness (t)=0.21 mm

relative permitivity() = 9.48 H/M

area (A)= 620 cm²

C=K A/t
