Induction motor
An induction motor is a type of electric machine. Here the stator coils produce a magnetic field, and this magnetic field induces a current,…
Equivalent two-terminal network
Equivalent two-terminal transformations are transformations that lead to the simplification of complex two-terminal networks with the smallest amount of L, C and R elements. These equivalent networks…
The concept of electric circuits
Electric circuits and electromagnetic field theory are essential for any electrical engineering field. Many branches such as power machines, electronics, communications and all modern…
Charge / electrical current
This post answers the question "What is the definition of electric charge?". The concept of charge is a basic one to explain the phenomena…
Voltage / power
To move an electrical charge in a specific direction you need to apply some force. This force is called by an external electromotive force…
Electric circuit elements / active elements
A circuit is an interconnection of circuit elements. And analysing circuits we determine voltages and currents through the circuit elements. Let's assume that all…
Resistors in series. Voltage divider circuit and equation
Resistance is an electric circuit component, which is characterised by energy losses in a circuit as heat, some mechanical work, or electromagnetic radiation. No…
Resistors in parallel. Current divider circuit and equation
Two or more resistors are said to be in parallel, if identical voltage is across all the resistors. In accordance to Kirhhoff's Law the…
Passive elements – inductance
Inductance is an ideal electric circuit component which is close to the inductor in its features and components - collecting the energy of magnetic…
