Why is positively charged terminal of battery considered at higher potential than negative terminal?
Answer Hello again Sarita, Electric potential is the potential energy per unit of charge associated with a static (time-invariant) electric field, also called the electrostatic potential, typically measured in volts. Electric potential may be conceived of as “electric pressure”. Where this “pressure” is uniform, nothing happens, just as we do not feel the static atmospheric pressure at sea level. However, where the pressure varies, it produces an electric field which creates a force that can move charged particles to different locations. Which terminal we call positive and which negative (and hence which terminal has higher potential) is a matter of definition. It was once defined as applying to a positive test charge and so that’s it. It could have been defined the other way around, but it makes no difference. One should only stick to one definition in order to avoid confusion. Hope this helps a bit.
