Нужна опять помощь

горе ученику))

Девочки кто безвоздмедздно за большое спасибо )) поможет мне. Есть текст, надо в нем найти кое какие предложения.

1) Перепишите предложения из текста в пассивном залоге и определите в каких временах он употребляется .

2) Найти и переписать все неправильные глаголы из текста. Дайте все формы этих глаголов

Сюда выкладываю, может девчонки хоть по одному абзацу , с мира по нитке))

Глядишь для вас практика)))

1. We know that the circuit is a complete path which carries the current from the source of supply to the load and then carries it again from the load back to the source. The purpose of the electrical source is to produce the necessary electromotive force for the flow of current through the circuit.

2. The path along which the electrons travel must be complete otherwise no electric power can be supplied from the source to the load. Thus we close the circuit when we switch on our electric lamp.

3. If the circuit is broken or, as we generally say ‘opened’ anywhere, the current stops everywhere. Hence, we break the circuit when switch off our electrical devices. Generally speaking, the current may pass through solid conductors, liquids, gases, vacuum, or any combination of these. It may flow over transmission lines from power stations through transformers, cables and switches, through lamps, heaters, motors and so on.

4. There are various kinds of electric circuits such as: open circuits, closed circuits, series circuits, parallel circuits, and short circuits.

5. To understand the difference between the following circuit connections is not difficult at all. When electrical devices are connected so that the current flows from one device to another, they are said to be connected in series. Under such conditions the current flow is the same in all parts of the circuit, as there is only a single path along which it may flow. The parallel circuit provides two or more paths for the passage of current. The circuit is divided in such a way that part of the current flows through one path, and part through another. The lamps in your room and your house are generally connected in parallel.
