Frequently asked questions
A battery charger is a device that provides a Direct Current Line (DC) to the battery to restore the used-up electrolyte. So ideally, when all the electrolytes of the battery supply are restored.
A chemical reaction between the metals and the electrolyte frees more electrons in one metal than it does on the other side. The metal that frees more electrons develops a positive (P) charge, and the other metal develops a negative (N) charge.
A circuit for charging a battery combined with a capacitor includes a power supply adapted to be connected to the capacitor, and the battery line. The circuit includes an electronic switch connected to the power supply.
Batteries are only able to store currents flowing in a single direction side. As a result, conventional batteries can only store direct current (DC) rather than alternating current (AC) supply.
The phones use DC to charge. Your phone charger converts the AC mains to a suitable DC voltage supply to charge your phone i.e. typically 5V.
