If the phase angle at an open breaker is equal to 1/10 of a cycle, what is this equivalent to in degrees?

To determine the equivalent degree measurement from a given phase angle expressed as a fraction of a cycle, it's important to understand the relationship between cycles and degrees in the context of a full rotation.

One complete cycle corresponds to 360 degrees. When the phase angle is expressed as a fraction of a cycle, you can convert it to degrees by multiplying the fraction by 360. In this case, since the phase angle is given as 1/10 of a cycle, the conversion to degrees is done as follows:

1. Calculate the fraction of the cycle in degrees:

[

\text{Degrees} = \left(\frac{1}{10}\right) \times 360

]

2. Perform the multiplication:

[

\text{Degrees} = 36

]

This result illustrates that a phase angle of 1/10 of a cycle is indeed equivalent to 36 degrees. Thus, selecting the choice indicating 36 degrees reflects an accurate understanding of the conversion from cycles to degrees. This conversion process is essential in electrical engineering contexts, where phase relationships play a critical role in analysis and application of electrical systems.
