Power factor = R/Z
But Z=R;as L is shorted.

Hence power factor= R/R

I completely agree with u sir..As the inductor is short circuited it behaves as a purely resistive circuit. Phase angle is zero. P.F=cos(0)=1.

In simple language, there will no lead or lag in the circuit, and the power factor will be 1 that the highest, or in other words ideal, that is required to save electricity bills in big companies.

When inductor is short only resistor is present and becomes load, when load appear as resistor then power factor is 1.

No loss of energy, only true power consumes by resistive load so power factor is 1.
No, lead or lag current or storage energy there is no reactive power.
Only true power seems to convert in a proportional into heat.
PF is 1.
