Homework SourseIf the resistive voltage drop is 340 volts and reactive volt
If the resistive voltage drop is 34.0 volts and reactive voltage drop is 70 volts what is the power factor?
If the resistive voltage drop is 34.0 volts and reactive voltage drop is 70 volts what is the power factor?
Solution
DEFINITION OF POWER FACTOR FROM POWER TRIANGLE
COS(PI)=(RESISTIVE VOLTAGE DROP)/(IMPEDENCE DROP)
IMPEDENCE DROP =((SQRT(RESISTIVE VOLTAGE DROP)^2)+(RECTANCE VOLT DROP)^2)
=SQRT((34^2)+(70^2))
SQRT(1156+4900)
SQRT(6056)=77.82
COS(PI)=34/77.82
0.436
