A lot of students come here to ask their doubts, now I have a question for the future engineers to whom early or later the world will deposit the future.
Power factor improve capacitors, what about resistor?
Power factor is improved by using capacitors but what about to use a resistor?
Assume an equivalent load with an impedance of 25 ohms with an angle of 25°
This yields to a power factor of the load equal to 0.9 (aprox.)
If I put a 25 ohms resistor in shunt with the previous load I get that from the source point of view the power factor now is 0.97
Why not to use resistors instead of capacitors to improve power factor?
