Battery

Nowadays, electricity plays very important role in our daily life.

The electricity is generated at the power stations and comes to our homes through the transmission and distribution lines.

And we can use it in our household appliances, like, TVs, freezes, fans, washing machine, etc.

But, there are some devices in which we can’t use this electricity directly.

For example, mobile phone, torche, watch, remote, etc.

Because, these devices work on the very low voltage.

Hence, to overcome this problem, a device was invented called battery.

Let’s discuss the battery.

The battery is a combination of two or more cells.

A cell has two electrodes as positive and negative terminal.

And the cell pushes the electric current from positive to the negative terminal. This is the way that current flows.

So, two or more cells are connected end to end to make battery.

Hence, there are primarily two types of arrangements: parallel and series arrangement.

Two or more cells are connected in parallel to increase the current rating in the combined cell..

In the parallel connection of the cells positive terminal of the one cell is connected to positive terminal of other.

For example, there are four cells connected in parallel, each cell is having .

Here, the current rating will be increased, but, the voltage will be the same.

Hence, if we want to increase the voltage of the combined cell, then, we have to make the series combination.

In which the positive terminal of one cell must be connected to negative terminal of the other.

Due to which, the voltage of each cell will be added to another and the final voltage will be the algebraic sum of each cell.

Hence, to increase the voltage of the battery, positive terminal of a cell should be connected to the negative terminal of other cell.

Therefore, the lead-acid battery is used in trucks, tractors, etc.

Because, it is the combination of lead-acid galvanic cells connected in series to increase the voltage.

The lead-acid battery is the secondary cell battery, means, it is rechargeable.

The lead acid battery is also used in invereters, but, there are less number of plates compared to the auto battery.

The collection of any similar things is called battery.

Hence, the collection of electrical storage cells is called battery, while it looks like one unit.

Hence, this is all about the battery.

Revision

The battery is a combination of two or more cells.

When the two or more cells are connected in parallel, then, it will give the same voltage.

And when the two or more cells are connected in series, then, it will give the algebraic sum of individual voltages.

Therefore, the lead-acid battery is used in trucks, tractors, etc. in which the cells are connected in series.
