Based on the total estimated load calculations, what is the current draw on the Study/Bedroom circuit? __________________________________________________________

Calculate the current drawn on the Study/Bedroom circuit based on the total estimated load calculations.
Answer to Problem 1R
The current draw on the Study/Bedroom circuit based on the total estimated load calculations is 9.4 amperes.
Explanation of Solution
Formula used:
Write the general expression to calculate the VOLT-AMPERES for single-phase.
Here,
E is the supply voltage, and
I is the current.
Rearrange the equation (1) to find the current I in amperes.
Calculation:
Refer to Table 14-1 in the textbook.
The total estimated load in VA for the Study/Bedroom outlet count in Circuit A21 is 1125 VA.
The single-phase supply voltage (E) is 120 V.
Substitute 1125 VA for VOLT-AMPERES and 120 V for E in equation (2) to find the current I in amperes.
Conclusion:
Thus, the current draw on the Study/Bedroom circuit based on the total estimated load calculations is 9.4 amperes.
