The electrons inside the battery move from the negative terminal to the positive terminal
The answer is: right
The automated informatics here talks about the movement of electrons inside the battery, as their movement is from the negative side to the positive side.
He explains that the atom consists of a nucleus containing positively charged protons, and electrons move between these nuclei.
Thus, the number of electrons increases at the negative terminal, making it negatively charged, while electrons move to the positive terminal, making it positively charged.
From this, the electrical circuit is connected to operate the device to be used.
