4 Factors affecting inductance

On August 13, 2018 by Areej

There are four basic factors of inductor construction determining the amount of inductance created. These factors all dictate inductance by affecting how much magnetic field flux will develop for a given amount of magnetic field force (current through the inductor’s wire coil):In this…

Relation between Magnetic fields and inductance

On August 11, 2018 by Areej

Introduction Whenever electrons flow through a conductor, a magnetic fields will develop around that conductor. This effect is called electromagnetism. Magnetic fields affect the alignment of electrons in an atom and can cause the development of physical force between atoms in space,…

Magnetic units of measurement

On August 11, 2018 by Areej

Introduction If the burden of two systems of measurement for common quantities (English vs. metric) throws your mind into confusion, this is not the place for you! Due to an early lack of standard-ization in the science of magnetism, we have been…

Difference between Voltage signal systems & Current signal systems

On August 10, 2018 by Areej

Voltage signal systems The use of variable voltage for instrumentation signals seems a rather obvious option to explore. Let’s see how a voltage signal instrument might be used to measure and relay information about water tank level: The ”transmitter” in this diagram…

3 Factors affecting capacitance

On August 10, 2018 by Areej

There are three basic factors of capacitor construction determining the amount of capacitance created. These factors all dictate capacitance by affecting how much electric field flux (relative difference of electrons between plates) will develop for a given amount of electric field force…

8 Transformer parameters

On August 8, 2018 by Areej

Introduction Transformers can vary, from a miniature high-frequency audio transformer to a large power transformer, the operating parameters are still the same. These can be divided into eight groups and are posted on the nameplate of any transformer of significant size: VA…

Introduction to Tachogenerators

On August 8, 2018 by Areej

An electromechanical generator is a device capable of producing electrical power from mechanical energy, usually the turning of a shaft. When not connected to a load resistance, generators will generate voltage roughly proportional to shaft speed. With precise construction and design, generators…

OPERATING LIMITATIONS OF TRANSFORMERS

On August 7, 2018 by Areej

Transformer Losses (Heat) The efficiency of power transformers is high, especially, for large transformers at full load. However, losses are present in all transformers. These losses may be classified as copper or I² R losses and core or iron losses.The thermal ratings…

Difference between primary and secondary cell

On August 7, 2018 by Areej

The primary cells make use of a chemical process which is not reversible. The cells have to be replaced after giving active service, e.g dry cells have to be discarded when discharged. The secondary cells on the other hand work on a…
