Please note that Amps (Current) and Watts (Power) are different measures and one cannot be converted into the other. Current (in a circuit) is one of the parameters for computing the Power taken by the equipment in the circuit. Hence it is incorrect to say How to convert Current into Power. Further the PF of a resistive load like an incandescent bulb (shown in the example) will be always unity and not 0.80. With Best Wishes.
Sometimes to test our knowledge interviewer asked this kind of questions so in that situation how you can give the answer that's things is explained in this Video Basically the video is just to explain how to find power rating And For example only i have taken 0.8 PF you can use 1 or 0.9 also according to the pf mention in the question
@@mohammedsalauddin3642 According to my knowledge we have to find power factors for each 3 phases seperately and power will be IV Cosπ1 + IVCosπ2 + IVCosπ3
@@mohamedhabeebullah9348 For the three phase you don't to find for each phase power watts , juz √3 ×415×Amps×0.8 that's all. If your going find for single phase power that time you don't need to include √3
Good explanation friend
Very useful bro👍🏻

Super sir 😊
This is the best way to learn. But what is the meaning of watt
Units of power
Sir in single phase p.f consider always unity
In real sense For electrician job description where does the Electrician practical compute voltage in to amps or current
Is the power factor is constant 0.8
For calculation i have used 0.8
In 3 pH supply how to calculate power factor?
Power factor

Just add √3×v×i cosπ
