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.

- B) A 60-Hz generator is supply ing 60% of P max to an infinite bus through a reactive network. A fault occurs which increases the reactance of the network between the generator internal voltage and the infinite bus by 400%. When the fault is cleared, the maximum power that can be delivered is 80% of the original maximum value. Determine the critical clearing angle for the condition described.arrow_forwardQ3) A: A generator operating at 50 Hz delivers 1 pu power to an infinite bus through a transmission circuit in which resistance is ignored. A fault takes place reducing the maximum powe transferable to 0.5 pu whereas before the fault, this power was 2.0 pu and after the clearance of the fault, it is 1.5 pu. By the use of equal area criterion, determine the critical clearing angle.arrow_forward4.
