Transformer is a device that convert AC to DC.

What is transformer?

It's not about the chemical activity that differs primary cell and secondary.
The chemical reactions in secondary can be reversible, so charging and discharging both are possible.
In primary reactions can't be reversible, so only discharging possible.

What is the chemical activity that takes place and the diff between the chemical activity taking place in primary cell and secondary cell. Can anyone explain me this?

DC: Direct current which is supplied from batteries not from transformer. The graph of DC is totally straight but in AC(Alternating current) is sinusoidal which is supplied from transformer.

Primary batteries can be used once because the chemical reactions that supply electrical current are Irreversible. In secondary batteries that the chemical reaction that supply electrical current are readily reversed. So in both batteries chemical reaction only takes place to generate dc.
