Question 313Electricity & Electronics - Assistant Engineer

The correct answer is B) 3011 amps. To calculate the ampere capacity at full load, we need to use the formula: Amps = Kilowatts / (Volts x Power Factor x √3). Given information: - Rated power: 2500 kW - Rated voltage: 480 V - Power factor: 0.8 Plugging these values into the formula: Amps = 2500 kW / (480 V x 0.8 x √3) = 3011 amps The other options are incorrect because: A) 2500 amps is too low, as it does not account for the power factor. C) 3125 amps is too high, as it does not use the correct power factor of 0.8. D) 5208 amps is too high, as it does not use the correct power factor of 0.8.
