ICSE Class 7 Physics Battery as a collection of cells connected in series
A direct current source has the fixed positive and negative terminals, e.g. a battery.
Cell is a primary source of electricity.
In a torch we use dry cell as the source of electricity.
A cell refers to a single anode and cathode separated by electrolyte used to produce a voltage and current.
Secondary batteries can be recharged; that is, they can have their chemical reactions reversed by applying electric current to the cell. This regenerates the original chemical reactants, so they can be used, recharged, and used again multiple times.
it only powers small appliances.
Primary batteries are designed to be used until exhausted of energy then discarded. Their chemical reactions are generally not reversible, so they cannot be recharged. When the supply of reactants in the battery is exhausted, the battery stops producing current and is useless.
