An electric cell is used to produce and supply electric energy. It consists of an electrolyte and two electrodes. Electrodes are used as terminals, they connect the cell to the circuit - current passes through the terminals and the bulb lights.
Cells can be connected in series, in parallel and in series-parallel. In order to increase the current capacity cells should be connected in parallel. In order to increase the voltage output cells should be connected in series. In case a battery has a large current capacity and a large voltage output, its cells are connected in series-parallel.
When cells are connected in series the positive terminal of one cell is connected to the negative terminal of the second cell, the positive terminal of the second cell - to the negative terminal of the third ... and so on.
When cells are connected in parallel their negative terminals are connected together and their positive terminals are also connected.
In case a cell has a trouble it stops operating or operates badly. This cell should be substituted by another one.

Mrs. Sara Winchester of San Jose, California, was a very strange woman who built one of the world’s most unusual houses. When she died in 1922, aged 85, she was living alone in a house that had more than 150 rooms and covered an area of land greater than 2.5 hectares.
Mrs. Winchester’s problem was that she believed that if she stopped adding rooms to her house, she would die. Therefore, she employed workmen to keep on building and was happy only when she heard the sound of building. The house, when she bought it in 1884, was quite small, but 38 years later it was huge.
When she bought it, the house had two floors. By the time she died, it had eight. It had three lifts, 48 fireplaces and nine kitchens – none of which was ever used. In total, there were 2,000 doors and 10,000 windows. There were also miles of secret passages and tunnels that no one, not even Mrs. Winchester, knew how to get in to or out of.
