You connect a 9 V battery to a capacitor consisting of two circular plates of radius 0.057 m separated by an air gap of 2.5 mm. What is the charge on the positive plate

Q = 3.254 x 10⁻¹⁰ C.

Explanation:

Given,

Potential, V = 9 V

Radius of circular plat re = 0.057 m

Air gap, s = 2.5 mm

Charge on the positive plate = ?

We know,

Q = C V

and

C = 36.15 x 10⁻¹² F

now,

Q = 36.15 x 10⁻¹² x  9

Q = 3.254 x 10⁻¹⁰ C.

Hence, the charge on the positive plate is equal to Q = 3.254 x 10⁻¹⁰ C.

  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
