Hi there!
Voltage in a series can be expressed by the following:

In words, the total voltage is equal to the sum of the individual voltage drops in a SERIES circuit.
We can solve for the total voltage:

Answer: Because of the polarity of water molecules
Molecular <u>cohesion</u> is the attraction that molecules have for others of their same type. Depending on the intensity of this attraction, a substance is in a solid, liquid or gaseous state.
In this sense, water (
) can stick to itself through hydrogen bonds, because a water molecule consists of 2 hydrogen atoms attached to 1 oxygen atom.
The oxygen atom tends to monopolize more electrons and keeps them away from hydrogen. Then, it can be said that a water molecule will have a negative side (oxygen) and a positive side (hydrogen).
<u>Thanks to this polarity</u>, water molecules can stick together with the formation of<u> hydrogen bonds</u> to attract a partial positive charge of hydrogen and a more electronegative atom, such as oxygen.
