Question

An alternator is delivering power
to a balanced load at unity power
factor. The phase angle between the
line voltages and the line current is --
Answer
A. 80 degree
B.60 degree
c. 30 degree
D. 0 degree​

Answer 1

Answer:

Option B is your correct answer

Answer 2

Answer:

Option (c) is the answer that is $\bold{30^{\circ}}$.

Explanation:

Line Voltage:-

Line voltage in a three-phase system is the potential difference between any two lines denoted by VL-L. If R, Y, and B are the three phases then the voltage difference between R and Y, Y and B, or B and R forms the line voltage.

Line Current:-

The measure of current in one phase before the star or delta arrangement of the component is called line current. In three phase balanced system, it may be R or Y , or B phase current. It is denoted by IL ampere.
