3^6 = 729
Power factor is an AC only term, and has no meaning for DC.
10 x 10 x 10 = 1000
Angle between v and i is 90 deg so, cos 90 = 0 Same for pure capacitor
As power factor decreases, kVA increases for the same amount of real power (kW) being used. This is because kVA is the combination of real power (kW) and reactive power (kVAR), and as power factor decreases, the amount of reactive power needed to support the load increases, leading to a higher kVA value. Conversely, as power factor increases, kVA decreases.
Same
I think you are referring to scientific notation in which you read numbers multiplied by ten and to the power of whatever. Example: You can write 1,000,000.0, or you can write 1.0 x 10 to the sixth power or for numbers with a value less than 1 Example: You can write 0.000001, or you can write 1.0 x 10 to the negative sixth power Either way you write it the number is the same.
4 to the second power
17 to the 3rd power as a product of the same factor is written 17 x 17 x 17
when voltage n current r in same phase(it happens when load is resistive) ,the power factor which denoted by "fi" is 1 .this condition is known as unity power factor
yes, it is possible. in fact in power systems all the generators do not run with same power factor.
106 is also known as one million. 1*106 = 1,000,000
