What is the total current draw when all six fluorescent luminaires are turned on?

Find the total current drawn when all the six fluorescent luminaires are turned on.
Answer to Problem 1R
The total current
Explanation of Solution
Discussion:
The recreation room consists of six lay in fluorescent luminaires. One fluorescent luminaire consists of four
Generally, the power factor of fluorescent luminaire lies between
Substitute
The current drawn by the six fluorescent luminaires is calculated as follows:
Substitute
One fluorescent luminaire is controlled by the 3-way switch. It also controls the stairway luminaire of
When the staircase luminaire is turned on, the value of
Substitute
Conclusion:
Thus, the total current
