What device is used to increase or decrease the amount of voltage from a source to a load or from a primary source to a secondary source?
If the primary source is AC, then that's the job of a transformer. If the primary source is DC, then doing that requires considerably more complex electronics.
What value for a transformer determines the amount of voltage that is stepped up or down?
For an ideal transformer, the voltage ratio is exactly the same as its turns ratio. So if, for example, there are twice as many turns on the secondary winding as there are on the primary winding, then the secondary voltage will be twice that of the primary and the transformer will be a 'step up' type.
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.
How step up transformer step up the input voltage?
It depends on the ratio of turns from primary to secondary.
How the input voltage is changed to an output voltage in a transformer?
Transformers work on the induction principal of the flux of the primary winding cutting the wires of the secondary winding. The amount of turns in the primary in relationship to the amount of turns in the secondary is the transformers winding ratio. This ratio is what governs the voltage value of the secondary winding.
What is the impedance of a transformer?
Impedance (Z) voltage is the amount of voltage applied to the primary side to produce full load current in the secondary side. It is usually listed on the transformer nameplate, expressed as a percent, and measured by conducting a short circuit test.
How does a step-down transformer work?
well the working of the step doen transformer depends on the number of turns on the secondary side of the transformer, now in the case of a step down transformer, the number of turns in the secondary windings are less as compared to the number of turns at the primary side/winding, so the amount of flux which links the secondary side of the transformer is also less resulting in the production of less amount of emf at the secondary side. hence the status of the voltage is decreased as compared to the voltage of the primary side.
How does a step down transformer work?
well the working of the step doen transformer depends on the number of turns on the secondary side of the transformer, now in the case of a step down transformer, the number of turns in the secondary windings are less as compared to the number of turns at the primary side/winding, so the amount of flux which links the secondary side of the transformer is also less resulting in the production of less amount of emf at the secondary side. hence the status of the voltage is decreased as compared to the voltage of the primary side.
What type of a device is used to increase or decrease the voltage in an electric circuit?
A transformer. A small example is the coil in a motorcar. A transformer, in a power line, only changes voltage in one direction under normal usage. At distribution voltages, about 8360 VAC, the voltage is monitored by a regulator. A regulator either increases or decreases the voltage automatically to insure the desired voltage is steady. This regulated voltage is then fed to transformers to provide customers with a regulated voltage at the desired voltage.
How do you find the secondary to primary transformer voltage ratio?
Turns Ratio = (Primary turns / Secondary turns) To calculate the turns ratio you have to actually know the number of turns or wraps on the primary and secondary coils. Nobody knows that usually the manufacture of the transformer doesn't even know. So what you can use as and equivalent is to calculate the voltage ratio. So what you typically need to look for is the Input voltage and divid it by the output volatge. Usually that would be as follows; (Primary Voltage/Secondary Voltage) = Voltage Ratio
Will a 30 watt transformer damage a device needing only 15 watts?
No, the rating of the transformer, in watts, is the maximum amount of energy that can be safely drawn from the device. Any wattage load up to that limit is safe to connect as long as the voltage is correct to the load.
What is step up and step down?
Usually refers to a transformer. A step up transformer increases the voltage and a step down decreases the voltage by an amount proportional to the ratio of the windings between Primary and Secondary. A 1:2 ratio is a step up and doubles the voltage. A 2:1 would be a step down and halve the voltage.
