What is understood by capacitance of a capacitor? A 900pF capacitor is charged to 100V by a battery. How much energy is stored in the capacitor?

Text Solution

Verified by Experts

`C= 900pF = 900xx10^(-12)F = 9xx10^(-10)F`
Stored energy `= (1)/(2)CV^2= (1)/(2)xx(9xx10^(-10))xx100^(2)`
`= 4.5xx10^(-6)J`
