According to EPA, more than 65% of sulfur dioxide is produce
in the US in a year, or over 13 million tons comes from electric utilities, and
93% of it is produced by the coal power plants.
China is known as the world’s
largest consumer of coal and as of this time, over 30% of the country
experiences acid rainfall because of the sulfur released.

Answer:
dynamic pricing policy
Explanation:
Dynamic pricing is the strategy of offering different prices to different customers. This could be based on purchase situations, past purchase behaviors,order ,size,timing, demand and supply levels and other factors.

The continuous neutral-current rating be for an autotransformer used to create a three-phase, it must be sufficient to handle the maximum possible neutral unbalanced load. 450.5.
<h3 /><h3>What is meant by autotransformer?</h3>
A grounding autotransformer is used to create a three-phase, 4-wire distribution system from a three-phase, 3-wire ungrounded system.
A three-phase autotransformer is a special type in which common winding is shared by the high voltage and low voltage. Three-phase AC is supplied at primary and output is collected at secondary. Three phase autotransformer is used for such applications where a small voltage is used in the distribution system.
Autotransformers are frequently used in power applications to interconnect systems operating at different voltage classes, for example, 132 kV to 66 kV for transmission. Another application in industry is to adapt machinery built (for example) for 480 V supplies to operate on a 600 V supply.
