Step Response of RL Circuits When a constant voltage is suddenly applied to an RL circuit, an increasing a current goes through the conductor and creates a magnetic field that expands with the increasing current. This current will reach a maximum value, and the magnetic field stop expanding. The expanding magnetic field induces a Counter-Electromotive Force […]
The matter is divided into molecules, which in turn are divided into atoms. These atoms are composed of two parts: nucleus and periphery.
1- In the nucleus of the atom there are: Positive charged protons, Neutrons which as its name suggests, have no electric charge or are neutral.
2- On the periphery of the atom there are: Negatively charged electrons.
