How many electrons must be removed from a conductor so that it acquires a charge of 3.5 nC ?

Obtain the expression for the energy stored per unit volume in a charged parallel plate capacitor.

How many electrons should be removed from a condutor so that it acquires a postion charge of 3.5xx10^(-9) C.

Define capacitance. of a capacitor. Give its SI unit. Prove that the total electrostatic energy stored in a parallel plate capacitor is 1//2 CV^2 ?

Keeping the voltage of the charging source constant, what would be the percentage change in the energy stored in a parallel plate capacitor, if the separation between in plates were to be decreased by 10% ?

A parallel plate capacitor consists of two thin conducting plates each of area A held parallel to each other at a suitable distance d. insulating medium is generally filled between the plates. When one plate of the charged capacitor is earthed the charges flows, a) from plate to earth b) from earth to plate c) no change in charge on the plate d) capacitor gets discharged

The question given below consist of an assertion (A) and a reason ( R). Use the following key to choose the appropriate answer to these questions from the codes (a), (b), ( c) and (d) given below: Both A and R are true and R is the correct explanation of A. Both A and R are true but R is NOT the correct explanation of A. A is true but R is false. A is false and R is also false. Assertion: The capacitance of a parallel plate capacitor decreases with the increase in distance between the plate of the capacitor. Reason:The capacitance of a parallel plate capacitor is C=(Aepsilon_0)/d .

A battery is used to charge a parallel plate capacitor till the potential differece between the plates becomes equal to the electromotive force of the battery. The ratio of the energy stored in the capacitor and the work done by the battery will be

The Millikan oil-drop experiment enabled the charge on the electron to be deterined. Two parallel metal plates P and Q are situated in a vaccum. The plates are horizontal and separated by a distance of 5.4 mm, as illustrated in fig. The lower plate P is earthed. The potential difference between the plates can be varied. An oil droplet of mass 7.7 xx 10^-15 kg is oserved to remain stationary between the plates , when palte Q is a t a potential of +850 suggest why plates p and Q must be parallel and horizontal and calcualte the charge with its gin, on the oil droplet.

How would you modify 5.0 nF parallel plate capacitor storing 25.0 J of energy so that it can store 50.0 J of energy without changing the charge on its plates?
