Ex. 3 Ex. 3 Choose the suitable words and translate the sentences: 1. The danger of electric shock (appears, disappears) when the conductor becomes (live, dead). 2. Current passes through faulty (earthed, unearthed) part of installations when the power is on. 3. Low accuracy of measurement is (an advantage, a disadvantage) of the measuring device. 4. The danger of electric shock (increases, decreases) in the wet and hot atmosphere. 5. No current flows through a (dead, live) conductor.
