The transformer needs AC at its input. The battery provides DC.
A transformer is used to transfer electricity from one circuit to another.
There are two types of transformers:- 1. Step-up transformer & 2. Step-down transformer. A transformer used to increase the voltage is called Step-up transformer. A transformer used to decrease the voltage is called Step-down transformer. Uses of step-up transformer:- in power supply stations, in picture tubes of TV, computer monitors, halogen lights, etc. Uses of step-down transformer:- in supply of electricity to homes, in the power supply to the low voltage devices like radio, music systems which are run by AC mains.

The current produced by batteries is direct current. Electronic devices need direct current; in this case, they need a power supply (often built into the electronic device itself), that converts the alternating current, from the electric outlet, to direct current.
A transformer is an electrical device that takes electricity of one voltage and changes it into another voltage. You'll see transformers at the top of utility poles and even changing the voltage in a toy train set.
transistor is switching device - no converting that input vales transformer is converting like step up/down that in voltage values
Transformers only work on a.c. This is because it's necessary to have a changing primary current in order to induce a voltage into the secondary winding.If you connect a battery across a transformer, it will not work. Furthermore, if the voltage of the battery matches that of the rated primary voltage, the resulting very large d.c. current is likely to overheat the primary windings and even burn it out.
An efficient transformer will convert more than 99% of the input energy into output energy, therefore wasting less than 1%.
Power input to a transformer = (voltage across the primary winding) x (current through the primary)Power output = (voltage across the secondary winding) x (current through the secondary)It doesn't matter whether the transformer is used in step-up, step-down or simple isolation.
NOOO!! you cant, it fried the battery i used to have and the computer in my seadoo!
In general, the lower the frequency of operation, the more weight must be added to the core laminations to avoid magnetic field saturation. This increases the size and weight of the transformer as the frequency decreases.
A voltage transformer (known as a 'potential transformer' in North America) is classed as an instrument transformer. It is used to reduce the voltage across a high-voltage load to a value that can be read (usually remotely) by an ordinary a.c. voltmeter, while electrically isolating that voltmeter from the high-voltage system for the purpose of safety. It can also be used to supply an input to a protection relay.
ya. we are using diode in a battery charger to convert ac into dc. 230v dc is step down by using step down transformer
stand by: battery powered circuit is used when AC input fails inline device: battery powered circuit is used continually
A chopper transformer is a kind of transformer used in an switching power supply.The primary input voltage of it is a Direct current (D.C) unlike any other ordinary step down transformer which uses an Alternating Current (A.C).Chopper transformer uses a switching transistor to produce a secondary voltage..
AC current or DC current can be used in transformers. A transformer is made of two coils of wire, the input coil induces a current into the output coil. Transformers change the voltage either up (step up transformer) or down (step down transformer). The amount of change in voltage is dependent solely on the number of windings in both coils in the transformer. DC transformers work exactly the same way AC transformers do.
I believe you meant transformer. If so it is a transformer used in high voltage circuits to reduce the current to a safer measurable value. It can be used as a direct input to a metering or protective relay to covert high currents to a lower value. It is used in AC circuits and typically encircles the conductor(s) it is monitoring, then works by using the expanding/ collapsing field which is the theory of induction used in transformer operation. It is the primary side of a "transformer" which only works when there is current flowing through it.
