Boundary Value Conditions in Electrostatics In electrostatics, which deals with stationary electric charges and their interactions, electric boundary conditions describe the behavior of the electric field at the interfaces between different media or regions. The two main types of boundary Read More …
The current flowing through a 300-m-long conducting wire of uniform cross section has a density of 3×〖10〗^5 A/m2. Find the voltage drop across the length of wire if the wire material has conductivity of 2×〖10〗^7 (S/m)
A 25-m long copper wire has a circular cross section with radius r=2cm. Given that the conductivity of copper is 5.8×〖10〗^7 (S/m), determine (a) the resistance R of the wire and (b) the power dissipated in the wire if the Read More …
Circuit Theory at High Frequency Why Circuit Theory Fails at High Frequency? Circuit theory, which is based on the principles of Kirchhoff’s laws and Ohm’s law, is a powerful and widely used tool for analysing electrical circuits at low to Read More …
Tunable Coplanar Patch Antenna In this article, we have discussed about Design Optimization of a Tunable Coplanar Patch Antenna. Due to the small size and simplicity of integration into contemporary wireless communication systems, coplanar patch antennas have grown significantly in Read More …
The Electric Field of a Direct Current (DC) The Electric Field of Direct Current (DC) and Alternating Current (AC). If a constant voltage is connected across a length of wire, the voltage will cause a proportional current governed by Ohm’s Read More …
