Reading and Speaking

I. Nataly and Alice were not at home from 4 till 6 o'clock yesterday. They were at the University. Read this passage through to find the answers to these questions.

1. What were the girls doing in the lab?

2. Were they using a multimeter or a tachometer?

3. What is a multimeter used for?

4. What are the main parts of a multimeter?

5. What are the students going to do next time?

Yesterday from 4 till 6 o'clock Nataly and Alice were working in the laboratory. They were studying different electrical devices and instruments. One of them, a multimeter, was on their demon­stration table all the time.

The multimeter is used for measuring three types of electri­cal units, namely: voltage, resist­ance and current. This device (see fig. 1) has several scales, a needle, a function selector switch, two leads, a crocodile clip and a probe.

 

Look at picture 2 – the girls were measuring the value of the  resistance at that moment. Alice was using two small crocodile clips to make a good connection between the meter and the resistor. While she was connecting the two leads to the resistor, Nataly was turning the switch to the resist­ance range.

The needle was indicating the value of the resistance on the ohnis scale. Next time they are going to measure the current. They will be using the same multimeter.
