Effect of Temperature On Resistance | Resistance Temperature Coefficient

Fundamental of Electrical Engineering | Effect of Temperature On Resistance| Resistance Temperature Coefficient Effect of Temperature On Resistance The electrical resistance changes with the change of temperature. The resistance does not only increase with the rise in temperature but it also decreases in some cases. In fact, for the different type of materials, the amount … Read more


Basic of Transformer A transformer is a static device which converts the alternating current energy from one voltage level to another voltage level. Why is the Transformer a static device? Unlike motor or generator where motion is required to generate output, but in the case of transformer both the winding i.e primary winding and secondary … Read more

Principle of DC Generator

Principle of DC Generator A D.C generator is a machine which converts mechanical energy into electrical Energy. A D.C generator produces D.C power or current.  D.C generator is based on the principle of Faraday’s Law of Electromagnetic Induction. Faraday’s Law of Electromagnetic Induction Faraday’s law of electromagnetic induction describes the relationship between magnetic field and an electric … Read more

Auto Transformer

Auto transformer basics  Normal transformers have two winding placed on two different sides i.e. primary and secondary. In Auto Transformer, one single winding is used as primary winding as well as secondary winding i.e primary and secondary shares the common single winding. The primary is electrically connected to the secondary, as well as magnetically coupled to … Read more
