Question 4

An ideal transformer is rated to deliver 430 kVA at 220 V (rms) to a customer, as shown in the figure. How much current, in kA, can the transformer supply to the customer?

Question 5

An ideal transformer is rated to deliver 422 kVA at 220 V (rms) to a customer, as shown in the figure. If the customer's load is purely resistive, what is the maximum power, in kW, that the customer can receive?

Question 6

An ideal transformer is rated to deliver 421 kVA at 220 V (rms) to a customer, as shown in the figure. If the customer's power factor is 0.9 lagging, what is the maximum usable power the customer can receive?

Question 7

An ideal transformer is rated to deliver 438 kVA at 220 V (rms) to a customer, as shown in the figure. If the customer requires 341 kW to operate, what is the minimum power factor with the given size transformer?
