The electrodes of a parallel plate capacitor are squares of side 25 cm, separated by 1.5 mm. the gap is filled with a dielectric material of relative permittivity 6.8. what is the plate charge when the potential difference between the plates is 140 v?

Explanation:

The side of the square = 25 cm =0.25 m

Area of square

Separation between the plate d = 1.5 mm

Relative permitivity k =6.8

The capacitance of the parallel plate capacitor is given by

Voltage across the capacitor V =140 Volt

So charge Q = CV

  the unit of the measure =

explanation:

  the property that is quantified by the energy needed per of material to raise the temperature by one.

  si unit of energy = joule (j)

  si unit of temperature = kelvin (k)

  si unit of mass of material = kilogram (kg)

the property that is quantified by the energy needed per of material to raise the temperature by one is called specific heat.

the unit of specific heat is

it is a negative acceleration
