Introduction to Electrostatics

Electrostatics is the branch of physics that deals with the study of electric charges at rest. This field explores the forces between charged particles, the electric fields they produce, and the potential energy associated with these interactions. Electrostatics is fundamental in various applications, ranging from everyday static electricity to advanced technologies in electronics and materials science.

Key Concepts in Electrostatics

  1. Electric Charge
    • Electric charge is a property of subatomic particles that causes them to experience a force when placed in an electromagnetic field. Charges can be positive or negative, and like charges repel while opposite charges attract.
  2. Electric Field
    • An electric field (E) is a region around a charged object where other charged objects experience a force. The strength and direction of the electric field can be visualized using field lines.
  3. Electrostatic Potential
    • Electrostatic potential (V) at a point in space is the amount of work done in bringing a unit positive charge from infinity to that point, without any acceleration.
  4. Capacitance
    • Capacitance (C) is the ability of a system to store electric charge per unit voltage. It is defined as C=QVC = \frac{Q}{V}C=VQ​, where QQQ is the charge stored and VVV is the voltage across the capacitor.

Electric Charges and Fields

Electric Charge

Electric charge is measured in coulombs (C). The fundamental unit of charge is the charge of a single electron, approximately −1.6×10−19-1.6 \times 10^{-19}−1.6×10−19 C.

Properties of Electric Charges

  • Conservation of Charge: The total electric charge in an isolated system remains constant.
  • Quantization of Charge: Electric charge exists in discrete amounts, multiples of the elementary charge eee.

Coulomb’s Law

Coulomb’s law quantifies the amount of force between two stationary, electrically charged particles. The law is expressed as:F=k∣q1q2∣r2F = k \frac{|q_1 q_2|}{r^2}F=kr2∣q1​q2​∣​

Where:

  • FFF = force between the charges (N)
  • kkk = Coulomb’s constant (8.99×109 N m2/C28.99 \times 10^9 \, \text{N m}^2/\text{C}^28.99×109N m2/C2)
  • q1q_1q1​ and q2q_2q2​ = magnitudes of the charges (C)
  • rrr = distance between the centers of the two charges (m)

Electric Field

The electric field (E) generated by a point charge is defined as the force (F) experienced by a unit positive charge placed in the field:E=Fq0E = \frac{F}{q_0}E=q0​F​

Where:

  • EEE = electric field (N/C)
  • FFF = force experienced by a test charge (N)
  • q0q_0q0​ = magnitude of the test charge (C)

Electric Field of a Point Charge

The electric field created by a point charge is given by:E=k∣q∣r2E = k \frac{|q|}{r^2}E=kr2∣q∣​

  • QQQ = charge creating the potential (C)
  • rrr = distance from the charge to the point where the potential is measured (m)

Capacitance

Capacitance is a measure of a capacitor’s ability to store charge per unit voltage. A capacitor consists of two conductive plates separated by an insulating material (dielectric).

Formula for Capacitance

C=QVC = \frac{Q}{V}C=VQ​

Where:

  • CCC = capacitance (F)
  • QQQ = charge stored (C)
  • VVV = voltage across the plates (V)

Factors Affecting Capacitance

  1. Plate Area (A): Larger plate area increases capacitance.
  2. Distance Between Plates (d): Smaller distance increases capacitance.
  3. Dielectric Material: Different materials affect capacitance based on their permittivity.

Capacitance of Parallel Plate Capacitor

The capacitance of a parallel plate capacitor can be calculated using:C=ϵ0⋅AdC = \frac{\epsilon_0 \cdot A}{d}C=dϵ0​⋅A​

Where:
