What type of current is used in mobile charger?

THe mbile charger takes a.c (alternating current) from power source and convers it to d.c(direct current) and feds it to mobile battery. The charger also steps down the voltage from the power line voltage 110v etc to very small voltages e.g3 v etc.


How can you use 1 transformer in Inverter and Battery charger?

Those are special type transformer used for both step down and step up in a single transformer ,they are specially designed . their wire thickness in both winding is thicker than ordinary step up or down transformer.and they are costly too.


What type of transformer used in bed lamps?

If the bed lamps use a low voltage bulb then the type of transformer will be a step down transformer.


How to make a charger from a VOLTAGE transformer?

A true voltage transformer is not designed for power applications; it will only supply so many VA to your charger. I would suggest you purchase a power transformer for this application. You'll need to rectify the AC voltage, and minimize the ripple. Rectifiers are used for the first part, capacitors, varistors, and power transistors can be used to minimize the ripple.


Can a Diode be used on a battery charger?

Yes, a diode can be used in a battery charger to prevent reverse current flow from the battery to the charger when it's disconnected. This protects the charger from potential damage.
