Question

In a circuit, a battery is used to _____.

Answer 1

Answer: Option (b) is the correct answer.

Explanation:

When we use a battery in a circuit then it provides voltage to the circuit. As a result there will be change in potential of electrons.

That is, when battery was not attached to the circuit then there was no potential of electrons.  But after the battery is attached then electrons start to move from there place.

Hence, there will be increase in potential of electrons.

Answer 2

The most likely answer that you'd get for this would be the third option which is to raise the potential of electrons.

As we all know, batteries are a source of power. By power, it means that it gives the needed energy for something to work, from toys to electrical appliances. Batteries have also different shapes and sizes, depending on what its purpose is, for what it is to be used, and as to how much power it holds. The energy that it stores is chemical energy and electrochemical cells would convert this energy to an electrical energy when a circuit is complete. Thus, it is used to raise the potential of electrons which would then form to an electric current sufficient enough to power the device it is attached on.
