Question

Charge 'Q'on a capacitor varies with voltage Vas shown in graph where 'Q' is along 'x' axis
represents V=½QV area of a triangle
and V' along y-axis. The area of triangle OAB represents​

Answer 1

Answer:

We know that

Q = CV

So area

A = 1/2 QV = 1/2 CV^2 = E

So it represents

Energy

Answer 2

The area of the triangle represents the amount of energy stored in it. i.e. U = 1/2 Q V

Explanation:

For the given triangle OAB:

we know that

U = 1/ 2 QV

This is the area given tin the triangle OAB.

So we can assume that

Triangle OAB = U = 1/2 Q V

This area represents the energy store in it.

Thus the area of the triangle represents the amount of energy stored in it. i.e. U = 1/2 Q V
