Eddy Current Theory and Applications
What is Eddy Current? According to Faraday’s and Lenz’s law, when varying magnetic field is subjected to a conducting loop, emf of different magnitude is
Maximum Power Transfer Theorem | Proof,Formula
Maximum power transfer theorem is a tool for determining the condition of maximum power transfer. The maximum power transfer theorem states that the source can
Ideal and Practical Voltage Source Explained
The voltage source supplies current to the electrical circuit. When the load is connected across the voltage source, the voltage source supplies current to the
What is Dependent Voltage Source?
The dependent voltage source is a four-terminal device whose output voltage is controlled either by circuit current or voltage. The output voltage is dependent on
What is Active, Reactive, and Apparent Power?
Active Power The power drawn by the load to do work is called the True power, Active power, or real power. When electrical energy is
What is Skin Effect? Factors affecting the skin effect
When the DC current flows through the conductor, the charge distribution throughout the conductor cross-section is uniform, and the current gets evenly distributed. Direct current
Crest Factor: Definition, Formula and its Significance
Definition- The crest factor, also known as the peak factor, is the ratio of the peak value to the root mean square (RMS) value of
