Magnetostriction : When ferromagnetic materials are magnetized, there are small changes in its dimensions. The phenomenon is called Magnetostriction. When subjected to rapidly alternating magnetic fields there is a rapid and continuus extention and...
Curie Point / Curie Temperature There is a critical Temperature called Curie Point, above which the ferro magnetic material lose their magnetic property and to become a paramagnetic material. The curie temperature is named...
Effects of low power factor 1. Load Current: Low power factor tends to increasing the load current. Power in an AC circuit can be given as: P = VI cosɸ Therefore, cosɸ = P...
Power Factor Power Factor is Defined as ‘the cosine of the angle between the voltage and current’. In AC circuit, the voltage and current are ideally in phase But practically, there exists a phase...
Resistance: The opposition offered by a substance to the flow of electric current is called resistance. The resistance offered by the circuit elements is essential to limit the flow of current. Resistance Unit is...
