Field due to an infinitely long charged wire

 Electric Field due to an Infinitely Long Charged Wire

Using Gauss's law, the electric field (E) due to an infinitely long charged wire with linear charge density λ is:


E = λ / (2πε₀r)


where:

= λ is the linear charge density.

= ε₀ is the electric constant.

= r is the distance from the wire.


The electric field lines are radial and perpendicular to the wire.

Electric Dipole

  Electric Dipole  An electric dipole consists of two equal and opposite charges separated by a small distance. It's a fundamental concept in physics. Key Characteristics:  1. Dipole Moment: p = qd, where q is the charge and d is the separation distance. 2. Electric Field: The electric field due to a dipole decreases rapidly with distance. 3. Torque : A dipole experiences a torque in an external electric field.  Applications:  1. Molecular Interactions: Electric dipoles play a crucial role in understanding molecular interactions and properties. 2. Polar Molecules: Molecules with a permanent electric dipole moment. 3. Dielectric Materials: Electric dipoles are induced in dielectric materials in an external electric field. Some examples related to electric dipoles: 1. Water Molecule: A polar molecule with a permanent electric dipole moment. 2. Electric Field Lines: Dipole electric field lines emerge from the positive charge and enter the negative charge. 3...

Continuous Charge Distribution

 Continuous Charge Distribution  A continuous charge distribution refers to a system where charge is spread over a region, such as a line, surface, or volume. The electric field due to a continuous charge distribution can be calculated using integration. Types of Continuous Charge Distributions: 1. Linear Charge Distribution: Charge is distributed along a line. 2. Surface Charge Distribution: Charge is distributed over a surface. 3. Volume Charge Distribution: Charge is distributed throughout a volume. Formula: The electric field due to a continuous charge distribution is calculated using the formula: E = ∫ dE Where:  dE = Electric field due to a small element of charge  Applications:  1. Calculating electric fields: For complex charge distributions. 2. Understanding charge behavior: In various systems, such as capacitors and conductors. Some examples of continuous charge distributions: 1. Uniformly Charged Rod: Calculate the electric field at a point on the axi...
