某一电压表的刻度线清楚，但刻度上的数字模糊不清了。某同学为了测定该电压表的量程和内阻，设计了如图甲所示的电路图。已知电路中其他仪器的主要参数如下：

电流表：A₁（量程2mA，内阻约20Ω）；A₂（量程3mA，内阻约10Ω）；滑动变阻器：R（阻值范围0-50Ω）；电源：E（电动势为4.0V，内阻约为0.2Ω）；电阻R₀=2.0×10³Ω。

（1）该同学接通电路后，调节滑动变阻器，他发现，当电压表指针达到三分之二满偏刻度时，电流表A₁、A₂的示数分别为I₁=1.0mA、I₂=1.5mA。若将两个电流表视为理想电表，不计其内阻影响，则该电压表的量程为______________，该电压表的内阻为______________。

（2）由于电流表A₁有内阻，该小组测出的电压表量程的测量值比真实值______________，内阻的测量值比真实值______________（选填“偏大”、“偏小”或“相等”）。

（3）若某同学依据图甲的电路图连接成图乙的实物图，并将滑片P置于滑动变阻器的最左端。由于实物连接电路有一处错误，该同学接通电路后，最可能造成损坏的的仪器是______________。请在乙图上改正电路连接的错误。

Society not only continues to exist by transmission, by communication, but it may fairly be said to exist in transmission, in communication. There is more than a verbal tie between the words common, community, and communication. (46) Men live in a community in virtue of the things which they have in common; and communication is the way in which they come to possess things in common. (47) What they must have in common in order to form a community or society are aims, beliefs, aspirations, knowledge—a common understanding—like-mindedness as the sociologists say. Such things cannot be passed physically from one to another, like bricks; they cannot be shared as persons would share a pie by dividing it into physical pieces. (48) The communication which insures participation in a common understanding is one which secures similar emotional and intellectual dispositions—like ways of responding to expectations and requirements.
Persons do not become a society by living in physical proximity, any more than a man ceases to be socially influenced by being so many feet or miles removed from others. (49) A book or a letter may institute a more intimate association between human beings separated thousands of miles from each other than exists between dwellers under the same roof. Individuals do not even compose a social group because they all work for a common end. The parts of a machine work with a maximum of cooperativeness for a common result, but they do not form a community. If, however, they were all cognizant of the common end and all interested in it so that they regulated their specific activity in view of it, then they would form a community. But this would involve communication. Each would have to know what the other was about and would have to have some way of keeping the other informed as to his own purpose and progress. Consensus demands communication.
We are thus compelled to recognize that within even the most social group there are many relations which are not as yet social. A large number of human relationships in any social group are still upon the machine-like plane. Individuals use one another so as to get desired results, without reference to the emotional and intellectual disposition and consent of those used. Such uses express physical superiority, or superiority of position, skill, technical ability, and command of tools, mechanical or fiscal. (50) So far as the relations of parent and child, teacher and pupil, employer and employee, governor and governed, remain upon this level, they form no true social group, no matter how closely their respective activities touch one another. Giving and taking of orders modifies action and results, but does not of itself effect a sharing of purposes, a communication of interests.
