What is the voltage output if the transformer is connected backwards?
It doesn't really matter which way around you use a transformer, the primary winding is ALWAYS whichever winding you connect to the supply, and the secondary winding is ALWAYS whichever winding you connect to the load. For either connection, the turns ratio will ALWAYS equal the voltage ratio for an ideal transformer (or close enough for a real transformer).
What device can be used to increase current in a DC circuit?
Transformer or instrument transformer. It can increase and decrease current output.
Difference between input and output transformer?
The 'input' side of a transformer is called its 'primary' side, whereas the 'output' side is termed its 'secondary' side. The ratio of its secondary to primary voltage is equal to the ratio of the number of turns in the secondary windings to the number of turns in the primary winding. So if, for example, a transformer's secondary winding has twice as many turns as its primary winding, then the secondary winding will produce twice the voltage applied to the primary winding.
If a dc voltage of 12v is added to the secondary of step down transformer and rating of transformer is 220 input and 12v output what will be the result from primary of transformer?
A DC voltage added to one side of a transformer has no effect on the other side.
What is the standard output current of a transformer when connected to an ac?
There is no 'standard' output current from a transformer. The secondary (output) current depends on the load, and should not exceed the rated secondary current. To find the rated secondary current, you divide the transformer's rated volt amperes by the rated secondary voltage. The above cited answer need more descriptive ; a) V/Z = I, b) V/Z = I + Magnetizing current of the transformer taken from Primary side of the transformer.

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.
Is a rear usb a input device?
A USB port is both and input and output port. Depends on what is connected to it as to which is functions as. Connect a camera and it is an input device. Connect a printer and it is an output device. Connect a printer/scanner and it is both.
100 volts of ac are put across a 100 trun transformer primary what will be the voltage output if secondry has 200 truns what is power in each coil?
You have a 2-to-1 step-up transformer. The voltage across the secondary winding is 200 volts. The power in the secondary winding is the power required by whatever 200-volt device you connect across that winding. The power drawn by the primary winding from the 100-volt AC supply is somewhat more than the power delivered to the device by the secondary, since some power is lost in the transformer wire and core. That's why the transformer hums and gets warm.
What is the load side of a transformer?
The load side of a transformer feeds the device, such as a light or motor. It is the output of the transformer. The input, or line side, provides the voltage that is to be transformed, either up or down, to supply the load side.AnswerA transformer's primary winding is connected to the supply voltage, and the secondary winding is connected to the load.
Will using an AC transformer with higher amps damage a kids toy?
Using a transformer with a higher capacity that is needed by the device connected to it will not damage the device. This is as long as the voltage the device needs is the same as the transformers output.
What are the output voltage and current of a transformer determined by?
The secondary (output) voltage is determined by the primary voltage and the turns ratio of the transformer. The secondary current is determined by the secondary voltage and the load resistance.
What is the point of a step up transformer?
A 'step-up' transformer is a transformer with more turns on its secondary winding than on its primary winding. It's secondary (output) voltage is, therefore, higher than its primary (input) voltage.
What is efficiency of a transformer?
Just like any other device . . . Output power/Input power
How can you see that the transformer is a step down or a step up?
If the primary voltage (input) is less than the secondary (output) then it is a step-up. If the input is greater than the output then it is a step-down transformer.
A transformer has a primary volt of 240v and a secondary volt of 48v what is the turn ratio?
