Ответ:
Power factor is 0.8517 or 85.17%
Step-by-step explanation:
We are given that in a parallel circuit,
, R=39kΩ and
=24kΩ.
That means the circuit has a resistor element, inductor element in parallel with 208V applied across the terminal.
Let us find the current through resistor,
And current through inductor,
milli amps.
Hence total current,![I_{T}= \sqrt{(I_{R})^2+(I_{T})^{2}} =\sqrt{5.33^{2}+8.667^{2}}=10.176](/tpl/images/0050/7008/90d27.png)
Now power factor=![\frac{I_{R}}{I_{T}}=\frac{5.33}{10.176}=0.8517](/tpl/images/0050/7008/b3fc7.png)
Hence power factor is 85.17% or 0.8517
