Quizplus · Accepted Answer

The total power in a balanced three-phase system is given by:$$P = 3VIcos(θ)$$where:* P is the total power in watts* V is the line voltage in volts* I is the line current in amps* θ is the phase angle between the voltage and currentIn this problem, we are given the line voltage (230 V) and the impedance (60 ∠35° Ω). We can use Ohm's law to find the line current:$$I = \frac{V}{Z} = \frac{230 V}{60 ∠35° Ω} = 3.83 A ∠-35°$$Now we can calculate the total power:$$P = 3VIcos(θ) = 3(230 V)(3.83 A)cos(-35°) = 1250.9 W$$Therefore, the correct answer is A.
