Answer:
1 - Define the problem
2. Do background Research
3 - Specify the requirements needed to fix/solve/complete the task at hand
Hope this helps!
Explanation:
1. The problem must be know before anything can be done
2. Do background Research to find if this issue has been solved or what can be done to solve it
3 - Find the requirements needed to fix the issue (ex. Size of replacement part)
The power factor of the circuit is 0.7071
<h3>What is Power factor?</h3>
Power factor (PF) is the ratio of working power, measured in kilowatts (kW), to apparent power, measured in kilovolt amperes (kVA). Apparent power, also known as demand, is the measure of the amount of power used to run machinery and equipment during a certain period. It is found by multiplying (kVA = V x A). The result is expressed as kVA units.
Power factor is expressed as the cosine of the phase angle.
The phase angle is given as 45°
Therefore the power factor in the circuit is cos45° = 0.7071
