Ideal transformer

Ideal transformer on no load  A transformer is ideal if it has No leakage flux No windings resistance No iron loss in core Ideal transformer can not possible physically. But it gives powerful tool in the analysis of a practical ...

Electrical transformer basics

The efficiency of electrical power transmission has improved for using higher voltages.  Alternating current has entirely replaced by the direct current for power transmission and distribution. For producing higher voltages ac generator is better than dc generator. Transformer is an ...

Inductor

An inductor is a passive two terminal element designed to store energy in its magnetic field. Inductor also called reactor or coil. It consists of conductor like wire wound into a coil. When current passing through the coil, energy is ...

What is capacitor?

A capacitor is an element which stores charges. It is a passive element as it stores energy. Michael Faraday invented capacitor. The unit of capacitance is Farad was the name of honor of Michael Faraday. In electronics, communication, power systems, ...

Linearity property in electric circuit

Linear property is the linear relationship between cause and effect of an element. This property gives linear and nonlinear circuit definition. The property can be applied in various circuit elements. The homogeneity (scaling) property and the additivity property are both ...

Delta to wye and wye to delta conversion

Sometimes we are not sure in electric circuits that the resistors are neither in parallel nor in series. See the circuit below here the relation between R1 resistor and R6 resistor is series or parallel we are not sure.

What is superposition?

When a circuit has two or more independent sources, we can determine the contribution of each source applying nodal analysis or mesh analysis. Another way is to find out the contribution of the independent sources (voltage or current) is to ...

What is circuit?

Circuit theory is important for electrical engineering, physical science, networking.  Circuit theory is the fundamental of electrical engineering. Every electrical engineering students should have clear concept about circuit. We transfer electrical energy one place to another through circuit. In our ...
