The most common meters

несколько немецких (книг).
One может также употребляться после местоимений this, that, another, the other для замены существительного в единственном числе, а после местоимения which - для замены существительного как в единственном, так и во множественном числе:
I have read this book, give me another one.
Я читал эту книгу, дайте мне другую.
I shall show you some books and you will tell me which ones you would like to read.
Я покажу вам несколько книг, и вы скажете мне, какие вы хотели бы прочитать.
One в притяжательном падеже переводится местоимением свой:
One should never forget ones promise.
Никогда не следует забывать своего обещания.

The most common meters used are the ohmmeter, the ammeter and the voltmeter. The ohmmeter is used to measure the value of resistance. It consists of a milliammeter calibrated to read in ohms, a battery and resistors. The meter is connected in parallel and the circuit is not opened when its resistance is measured. The readings on the scale show the measured value. The ammeter is used to measure the value of current. When the ammeter is used the circuit should be opened at one point and the terminals of the meter should be con - nected to it. One should take into consideration that the positive terminal of the meter is connected to the positive terminal of the source; the negative terminal -- to the negative terminal of the source. The ammeter should be connected in series. The readings on the scale show the measured value.
