For circuit used for transporting
electric power, a low power factor
implies large power loss in
transmission. Explain.

Open in App

Solution

Dear student,
We know that,

P = E_rmsX I_rms cosɸ.

Therefore, to transport a given power P, low power factor (means cosɸ) means a larger current through the transmission line, resulting in large line power loss I²R.

Regards
