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
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.
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
Yes if the power factor is unity.Additional AnswerOnly if the load is purely resistive. For a resistive-inductive (R-L) load, the current will reach its maximum value after the voltage reaches its maximum value, and we say the current is 'lagging the voltage'. For a resistive-capacitive (R-C) load, the current will reach its maximum value before the voltage reaches its maximum value, and we say the current is 'leading the voltage'.The angle of lag or lead is called the circuit's 'phase angle' and the cosine of that angle is termed the circuit's 'power factor'. So, for a purely-resistive circuit, the phase angle is zero and the power factor is 1 ('unit'). For R-L circuits, the power factor is less than 1, and is described as 'lagging'. For R-C circuits, the power factor is also less than 1, and is described as 'leading'.
