Final answer:
The power consumption of the electric train with a current of 1,880 A and 990 V is 1,861,200 watts or 1.8612 megawatts.
Step-by-step explanation:
To calculate the power consumption of an electric train running on 990 V with a current of 1,880 A,
you can use the formula P = IV,
where P represents power, I represents current, and V represents voltage.
Plugging in the given values,
we get P = 1880 A * 990 V = 1,861,200 W.
Therefore, the power consumption of the electric train is 1,861,200 watts or 1.8612 megawatts.
