Power Factor Correction
Capacitive Power Factor correction is applied to circuits which include induction motors as a means of reducing the inductive component of the current and thereby reduce the losses in the supply. There should be no effect on

Advantages and disadvantages of cold lime soda process
Cold lime soda process, when hard water is treated with calculated amount of lime [Ca(OH)2] and soda ash (Na2CO3) at room temperature 25ºC, the soluble Ca and Mg salt present in hard water are chemically converted into
Difference between Synchronous Motor and Induction Motor
Synchronous Motor Induction Motor Synchronous motor construction is complicated. Induction motor construction is simpler, particularly in case of cage rotor. This is Not self starting. This is self Starting Separate DC source is required for rotor excitation.
What is LED light?
LED lights are the latest technology in energy efficient lighting. LED stands for ‘Light Emitting Diode’, a semiconductor device that converts electricity into light. LED lights are super energy efficient, using approximately 85% less energy than halogen
How to find Amp (Amperes) in ac and dc
E = Voltage I = Amps PF = Power Factor Eff = Efficiency HP = Horsepower Formula for finding Amperes when Horsepower is known in direct current (dc) and alternative current (ac): To Find (Formula) Direct Current
Difference between BJT And JFET
BJT JFET Unipolar device (current conduction is only due to one type of majority carrier either electron or hole). Bipolar device (current condition, by both types of carriers, i.e. majority and minority-electrons and hole). The operation depends
Types of Transformers Based on the Value of K
Transformation Ratio (K) The transformation ratio for voltage is defined as the ratio of secondary voltage to the primary voltage of a transformer. It is denoted by K. Turns Ratio of the Transformer The turn’s ratio of
