What is inductance?

  It is a property of a circuit element called inductor to store energy in the magnetic field when current passes through it. A basic inductor can be made by simply twisting a coil of a certain length. If current passes through an inductor, an electro magnetic field is formed.  Any change in the magnitude … Read more

What is voltage?

  There are two types of charges namely positive charge and negative charge. As we all know these charges are opposite and they attract . A work is done to separate these two charges through a specific distance. When these two charges are separated from each other certain amount of energy is stored in them in … Read more

How do Fuel Cells Work?

Fuel cells cleanly and efficiently convert chemical energy from hydrogen-rich fuels into electrical power and usable high-quality heat in an electrochemical process that is virtually absent of pollutants. What are fuel cells? Fuel cells are non-polluting energy resources. It cleanly and efficiently converts chemical energy from hydrogen-rich fuels into electrical power. Each fuel cell consists … Read more
