【A series connection and parallel one by dry cells】Ⅲ

With a way of connecting,amount of electric resistance changes.☝

When connecting two miniature bulbs with a dry cell,amount of electric resistance changes.💡

If connecting the two bulbs under the same condition,the bulbs are considered to be an obstacle,it means electric resistance,and as for whole of electric resistance,series connectings becomes bigger.😚

It's a law of ohm.When being same voltage, the bigger the electric resistance is,the less electric current is.In short,as for the electric current,the series connecting is less than parallel one.💡

If connecting two miniature bulbs with a dry cell, brightness of the bulbs becomes darker than a single bulb.😃

It's why only half voltage of the single bulb is loaded to two each bulb.It's the series connecting.😱

I'll express parallel connecting under the same condition next time.🙋
