在图12所示的电路中，电源电压保持不变。闭合电键S，滑动变阻器的滑片在某一位置时，电压表示数为12伏，电流表示数为1.2安。求：

（1）电阻R₁的阻值；

（2）当滑动变阻器的滑片向右移动到另一位置，电压表示数变化2伏时的电流表示数I′；

（3）若把电压表改接在滑动变阻器R₂的两端，当滑动变阻器的滑片在中点（即滑动变阻器连入电路中的阻值为滑动变阻器最大阻值的二分之一）和最右端时，电压表的示数分别为12伏和15伏，那么电源电压U和滑动变阻器的最大阻值R_2max为多大？

发起人应承担的责任

For a long time, a boy wondered why his next-desk-pal was always the first in the class, whereas he could only rank the 21st. At home, he asked his mom, “Am I more stupid than other kids? How come I always lag behind? I just can’t come up with an answer.” Mom was aware that her son’s self-respect had been damaged by the ranking system, but she didn’t know what to say to help.

She was tempted (想要) to say that intelligence differs and that yes, her son’s friend really was the smarter boy. But that would have so upset her son. Thank goodness she resisted the temptation to say it.

Her son and his friend went on to high school that year, but despite trying as hard as he could, her son’s friend still outdid him. But she was proud of her boy for his hard work, sincerely proud. It was around this time she decided to take him on a trip to the seaside. On the trip, she at last found an answer for him.

Today her son no longer cares about rankings. He doesn’t have to, for he himself is now the top of the class – at the top national university he attends. Invited to speak to his old high school, he mentioned a valuable childhood experience: “Once, on a trip to the sea, my mother and I were lying on the beach. She pointed to the sea and said to me: ‘Do you see the seabirds fighting for food out there? When a wave comes near, the little birds rise quickly. The “clumsy” seagulls (海鸥) are far less agile (灵活的) and have to struggle to get away from the wave. But these “clumsy” birds prove to have the biggest, strongest wings, which open the widest and allow the bird to travel the furthest. When the season changes, they leave for foreign shores, leaving the little birds behind. Son, I have a feeling that you are one of those seagulls.”
