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.

Answer: Demand characteristics.
Explanation:
Demand characteristics are the traits shown by participant of the research and experiment in which they behave according to the expectancy of researcher or experiment so that aim of the research can be accomplished .This creates biasness in research process and decrease validity of the experiment.
According to the question, John's positive reply to the situation where someone need helps if his/her car is broken displays the impact of demand characteristics .In actuality , he would probably not help the person by stopping and he just answered in positive manner to support the study.Thus, the reply is biased.
