Question

Which of the following accurately describes the energy stored on a parallel plate capacitor?

A) The energy is inversely proportional to the charge stored on the capacitor.
B) The energy is directly proportional to the potential across the capacitor.
C) The energy is directly proportional to the capacitance of the capacitor.
F) The energy in proportional to the square the charge stored on the capacitor.

Answer 1

The energy stored on a parallel plate capacitor is directly proportional to the potential across the capacitor.

Step-by-step explanation:

The correct answer is B) The energy is directly proportional to the potential across the capacitor.

In a parallel plate capacitor, the energy stored is given by the formula:

E = (1/2) * C * V^2

Where E is the energy, C is the capacitance and V is the potential across the capacitor. In this formula, we can see that the energy is directly proportional to the square of the potential.

Answer 2

F) The energy in proportional to the square the charge stored on the capacitor.

Step-by-step explanation:

As we know that the energy stored between the plates of capacitor is given by the formula

`U = (1)/(2)CV^2`

also the charge stored between the plates is given as

`Q = CV`

now we use both equations then we have

`U = (Q^2)/(2C)`

since the capacitance of the capacitor is always constant here so we will have correct answer as

F) The energy in proportional to the square the charge stored on the capacitor.
