Will transformer operate if a battery is used for the input voltage across the primary?

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.

When transformer voltage regulation will be zero it operate at?
A transformer will operate with a voltage regulation of zero when it is not supplying a load.
What is the incoming voltage from the current source to the transformer called?
the incoming voltage from the current source to the transformer is called primary voltage.....
What are step-up and step-down transformers?
A Step Up Transformer is one whose secondary voltage is greater than its primary voltage. This kind of transformer "steps up" the voltage applied to it.The Step Up transformer is designed to increase the voltage from the primary winding to the secondary winding.A Step-Down transformer is one whose secondary voltage is less than its primary voltage. The step down transformer is designed to reduce the voltage from the primary winding to the secondary winding. This kind of transformer "steps down" the voltage applied to it.The basic equation for stepping up or stepping down the voltageNp/Ns is known as the turns ratio.The induced voltage in the secondary winding (Vs) is in proportion to the primary voltage (Vp) and is given by the ratio of the number of turns in the secondary (Ns) to the number of turns in the primary (Np).I to answer basic transformer questions.
What is the different between et up and set down transformer?
the difference between a step up transformer and a step down transformer is that, in a tsep up transformer, the voltage secondary is greater than the primary side but in a step down transformer, the voltage secondary is lesser than the primary side
What type of voltage is passed trough a transformer?
Voltage doesn't 'pass through' anything! Voltage is another word for 'potential difference', and is measured between two points in a circuit. For a transformer to work, it's necessary to apply an a.c. voltage across the transformer's primary terminals.
When transformer voltage regulation will be zero it operate at?
A transformer will operate with a voltage regulation of zero when it is not supplying a load.
The incoming voltage from the current source to the transformer is called what?
The incoming voltage from the source to the transformer is called primary voltage.
Can a flyback transformer be powered by nothing but a car battery and wires?
A transformer is an AC device in that it requires a changing current to be input in order to see an output. Attaching a 12V battery to the primary side of the transformer will generate a voltage on the secondary for a short amount of time. Once the primary current has risen to a stable level, there will be no output voltage on the secondary. There will also be voltages on the secondary and the primary when the battery is disconnected from the transformer. A flyback transformer relies on an AC current at the primary to generate a high voltage at the secondary output. Circuitry to make changes to the primary current will be needed in addition to the battery. Warning: removing the battery from the primary winding of the transformer is liable to generate a very high voltage across the primary coil as well as the secondary. In some cases, they can be lethal. Do not experiment with transformers unless you are properly qualified and supervised.
What is meant by rated voltage?
the voltage which is mainly applied to primary side of the transformer is called rated voltage.Answer'Rated voltage' is the nominal voltage at which an electrical device has been designed to operate.
When voltage regulation will be zero it operate it?
A transformer will operate with a voltage regulation of zero when it is not supplying a load.
What is the incoming voltage from the current source to the transformer called?
the incoming voltage from the current source to the transformer is called primary voltage.....
How do you calculate transformer voltage ratio test?
Secondary voltage / primary voltage
Can infinite voltage be given at transformer primary?
no, infinite voltage can't be given to the primary of the transformer....if the secondary is connected to the load, then over voltage will damage the load, if secondary is open circuited, then the infinite voltage can breakdown the transformer internal insulation,
What Device used to select amount of voltage in primary coil of step up transformer?
There is no selective device to determine the amount of voltage. A transformer is selected by the voltage available at the site for the primary and the load on the secondary side of the transformer.
How voltage is measured in potential transformer?
By connecting a voltmeter across the secondary terminals of the voltage/potential transformer. The transformer acts to reduce the voltage applied to its primary winding, while electrically-isolating the primary (usually high-voltage) circuit from the voltmeter.
If a transformer has 20 primary windings and 100 secondary windings and the secondary voltage is 25 what is the primary voltage?
Transformer step-up/step-down voltage is turns-ratio, so if a transformer has 20 primary windings and 100 secondary windings (a turns-ratio of 1 to 5) and the secondary voltage is 25, then is the primary voltage is 5.
What are the voaltg in isolation transformer?
The function of an isolation transformer is to electrically-isolate the secondary circuit from the primary circuit, without changing the voltage levels. So, its secondary voltage will be the same as the primary voltage.
