Is a battery potential energy?
Explanation
A potential difference is set up between the plates of a parallel plate capacitor by a battery and then the battery is removed. If the distance between the plates is decreased, then how the (a) charge (b) potential difference (c) electric field (d) energy and (e) energy density will change?
From a battery of potential difference 20 V, current 3 A flows through a wire for 90 min. Find the electrical energy supplied by the battery.
For a real battery the work done by battery is equal to increase in electrical potential energy of a positive charge as charge moves from negative terminal to positive terminal of battery
Is this above statement true. ??
