На энергетическом факультете нас готовят работать в области электротехники, электроснабжения промышленных предприятий, городов и сельской местности. Инженеры – энергетики должны решать многие проблемы. Они должны знать технику высокого напряжения и бытовые электроприборы, электромоторы различных типов и изоляторы, и многое другое электрооборудование. После окончания учебы в университете мы сможем работать на электростанциях или в энергораспределительных центрах страны.
Voltage applied to your body may result in an electric shock. You will get it if you touch “live” conductors when the power is on. When you touch a wire conductor with both hands the resistance of the body to the conductors is from 10,000 to 50,000W.
When you touch a conductor with one hand, the resistance is much higher. The higher is the body resistance the smaller is the current that can flow through the body.
Take it into consideration and work with only one hand if the power is on. Do not let the other hand touch the conductors! Or work on the circuit with the power off.
