The larger the **Wh** rating of a battery, the more electrical energy it can store. If the voltage across a capacitor is halved,the energy stored in it becomes one fourth of the original value. Kirchoff’s current law states that the sum of currents entering a node in an electric circuit is equal to the sum of currents leaving the node.
