Conductors in the external electric field. Faraday’s law
This post is about Fardey's Law and conductor's behaviour and features in the external electric field. Let’s consider a case when the neutral conductor…
Capacitors and capacitance
A capacitor is a system consisting of a two conductors, where an isolated electric field is created between two equal conductors , opposite charges.…
Signal sources, noise sources, coupling mechanisms
This post answers the question how to reduce noise in a circuit. During circuit design it is important to make a proper connection between…
Filtering and amplification
This post answers the question what is filtering in signal processing. The first step towards a proper measurement system is shielded, grounded and wired…
Energy of a capacitor and an electric field
Elementary work of external forces to move charge dq in electric field of a capacitor dA=dq*(φ1-φ2)=dqqC Total work is A=∫0QdqqC=Q22C this work determines total…
Dielectrics
We will cover the topic of dielectrics in the Electronic Materials chapter in detail. Here is a brief explanation of the main terms about…
Magnetic reluctance position sensors
This magnetic structure is very simple due to its consistency and is very wide spread in the application of measuring linear and angular velocity.…
Magnetic interaction
In this chapter we will cover magnetic interaction. Magnetic interaction shows how charged particles are interacting with each other. A charge moving in a…
Ampere law
The scientist Ampere has empirically discovered the interaction force for two parallel wires, dependent on the force being reversely perpendicular to the distance between…
