Прочитайте текст и выберите утверждение, соответствующее содержанию текста
The students of the technical school were carrying out the experiment with a multimeter in the lab last week. They were checking a mains socket in the wall and they were following all the safety instructions. Paul was using two probes that time. While he was inserting them into two terminals of the socket, his groupmate Alex was turning the function selector switch to the VAC (voltage alternating current) range. The needle was indicating the pressure of electricity, i.e. the voltage in the mains. Everybody was watching the indications on the volts scale. It was 220 volts. Next time they are planning to measure the current in a table lamp.
