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.…
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 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…
BJT definition and characteristics
BJT transistor is a three terminal semiconductor device, based on three layers of p and n layers, with different doping concentration. BJT transistor can…
Magnetic induction vector circulation
There are two methods of magnetic induction B calculation. The first method is using the Biot-Savart-Laplace and induction superposition principle. The second method is…
Electromagnetic induction
In 1831 British physicist Michael Faraday was analysing all the cases of electromagnetic induction phenomena – phenomena of current induction in a conductor along…
Self-induction – Inductivity
Electromagnetic induction occurs in different ways. For example, when current changes in the circuit, there is different kinds of EMF that occurs in the…
