The capacity of the parallel plate capacitor increases when A. Area of the plate is increased OB. Distance between the plate increased C. Area of the plate decreased OD. none of the option

The correct answer is A. Area of the plate is increased.<br /><br />The capacity of a parallel plate capacitor is given by the formula:<br /><br />C = ε₀ * (A / d)<br /><br />Where:<br />- C is the capacitance of the capacitor<br />- ε₀ is the permittivity of free space (a constant)<br />- A is the area of the plates<br />- d is the distance between the plates<br /><br />From the formula, it can be seen that the capacitance (C) is directly proportional to the area of the plates (A). Therefore, increasing the area of the plates will increase the capacitance of the parallel plate capacitor.<br /><br />Option B, "Distance between the plate increased," is incorrect because increasing the distance between the plates will decrease the capacitance.<br /><br />Option C, "Area of the plate decreased," is also incorrect because decreasing the area of the plates will decrease the capacitance.<br /><br />Option D, "none of the options," is incorrect because option A is the correct answer.
