Электрический ток

электрический ток это движение электронов. электрический ток идет по проводу и наполняет его. Напряжение - это причина движения электрического тока, без напряжения нет тока, без тока нет напряжения.  в качестве источников напряжения используют аккумуляторы, гальванические элементы, генераторы. Единицей измерения электроэнергии является вольт, электрический ток измеряется в амперах, единицей электрического сопротивления является Ом. Для измерения электрического напряжения используется вольтметр. Вольтметр подключается параллельно нагрузке (потребителю).

My best friend was born on 28th of February. It is the end of the winter. My friend invited many his friends. we were at his place. he lives not in a flat, but in their own house. Now he lives alone because his parents are abroad because of work.

So there were many teenagers. we decided to cook barbecue in the yard. I cook it very well so i was like chief cook.

All the guests came with different gifts for my friend. But my gift was special. I presented him a rare edition of his favourite book with the author's signature on it. he was very happy!

EVerybody liked my barbecue, then we danced a lot. in midnight there was great firework. after that we ate the birthday cake and drank tea.

My friend liked his birthday party.
