Potential is the measure of the amount of energy that can be transferred per unit charge between two points. It is also known as voltage.
In a battery, chemical reactions convert chemical energy into electrical energy, creating a potential difference between the positive and negative terminals. This potential difference is what allows charges to flow from one terminal to the other, creating an electric current.
The unit of potential is the volt (V), named after Italian physicist Alessandro Volta.
The potential difference between two points in an electric circuit determines the rate at which electric charges flow. Higher potential differences result in a faster flow of charges, while lower potential differences result in a slower flow of charges.
Yes, potential difference can be measured using a voltmeter, which is a type of electrical measuring instrument. It is connected in parallel to the two points between which the potential difference needs to be measured.
