Explanation Given Info: The dimension of the plates of capacitor is 5.0 mm × 5.0 mm . Convert dimensions from centimeter to meter. 5.0 mm × 5.0 mm = ( 5.0 mm × 1 m 1000 mm ) × ( 5.0 mm × 1 m 1000 mm ) = 0.005 m × 0.005 m Separation between the plates is 0 .10 mm . Convert millimeter into meter. 0 .10 mm = 0 .10 mm × 1 m 1000 mm = 1 × 10 − 4 m Capacitor is attached with a battery of potential 9V . Formulae used: Find the Capacitance of the plates ( C ) : Formula to find the capacitance is, C = ε 0 A d (I) Here, • ε 0 is the permittivity of the free space, • d is the separation between the plates, • A is the area of the plates it’s expression is, A = a × b (I) Here, a , b are the dimensions of sides. Substitute the value of A in equation (II), C = ε 0 ( a × b ) d (II) Formula to find electric field is, E = V d (III) Formula to find charge on capacitor is, Q = C V (IV) Calculation: Find Capacitance: Substitute the value 8.85 × 10 − 12 Fm -1 for ε 0 , 1 × 10 − 4 m for d and 0.005 m × 0.005 m for a × b in the equation (II) to find C , C = 8.85 × 10 − 12 Fm -1 × 0.005 m × 0.005 m 1 × 10 − 4 m = 2 To determine (b) The capacitor’s potential difference, electric field and charge after Mylar is inserted.

Dielectric Constant Of Water

Water constitutes about 70% of earth. Some important distinguishing properties of water are high molar concentration, small dissociation constant and high dielectric constant.

Electrostatic Potential and Capacitance

An electrostatic force is a force caused by stationary electric charges /fields. The electrostatic force is caused by the transfer of electrons in conducting materials. Coulomb’s law determines the amount of force between two stationary, charged particle…
