问题:

某同学做“测量小灯泡的电功率”的实验,器材有:6V蓄电池、电流表(0~0.6A、0.3A)、电压表(0~3V、0~15V)、滑动变阻器(50Ω、1.5A)、额定电压为2.5V的小灯泡(正常发光时的电阻约为7Ω)、开关各一个,导线若干。

(1)该同学电压表应该选择        的量程。

(2)他连接的实物电路如图所示,闭合开关前应把滑动变阻器的滑片调到       (填“C”或“D”端)。

(3)闭合开关后,小超发现小灯泡始终不发光,电流表的示数为零,电压表的指针迅速超过最右侧的刻度线,产生此故障的原因可能是下列情况中的             。(填字母代号)

A.小灯泡短路  

B. 小灯泡的灯丝断了    

C. 小灯泡的灯座接触不良

D. 电压表的正、负接线柱接反           

E. 变阻器滑片放在了最小阻值处

(4)排除故障后,他调节滑动变阻器使小灯泡正常工作,此时电流表的示数如图所示,则该小灯泡正常工作的电流         A。该小灯泡的额定功率是       W。

There are plenty of beauty schools throughout the country that can help you to start a career in cosmetology(美容业). Nowadays, young people may not be able to afford a four-year college. Students can look forward to attending a beauty school program which will only take a few months to complete and start their career right away to earn money.

There can be many benefits of going to beauty school. The expense is much less than attending a four-year university. Besides, attending beauty school is mostly a hands-on(动手的) experience which appeals to many people. Some students don’t like sitting all day listening to lectures and then having to study at night. What’s more, most beauty school programs keep up with the changing trends and fashion. So you will always be working on different hair types which can be fun and will give you a lot of experience throughout the years of your career.

If you are worried about finding a job after graduation, many beauty schools will offer assistance for immediate job placement and give you peace of mind that you will not be stranded looking for a job. Most colleges and universities are not equipped to do that because of the large number of graduates each year.

Cosmetologists will also make a good salary. The average salary will depend on your location, but you may earn a salary around $3,000 — $3,500 a month. This is not including tips which could be $600 or more a month.

Not only can young people go to cosmetology school, but people of all ages can start this career. As you can see, there are many benefits of beauty schools that can be the perfect opportunity for anyone to become a great cosmetologist.
