To purchase a Transformer are given input voltage output voltage and wattage sufficient?
How much does it cost? Will it fit in the space provided? Is cooling for it provided? When can it be delivered? Does it need provision for tapping for minor voltage changes? Does it need provision for remote monitoring? Voltage variation with load. Conformance with applicable standards. Frequency. A TRANSFORMER IS A PASSIVE DEVICE SO YES THE INPUT VOLTAGE IS NECCESSARY FREQUENCY OF OPERATION THE KVA OUTPUT IS ALL THAT YOU NEED.
When a PNP transistor is connected in a circuit in the manner it can be used as a power amplifier because?
the output voltage will be much larger than the input voltage
How much energy is used by a transformer?
An efficient transformer will convert more than 99% of the input energy into output energy, therefore wasting less than 1%.
Why is a transformer necessary?
A transformer is not 'necessary'. The human race evolved, and developed cultures, societies, disease resistance, and technology, without ever seeing a transformer. But there are specific situations in which desirable things can be accomplished much more effectively and efficiently with a transformer than with any other device or method. Here are a couple of examples: -- If the voltage you have available is not the voltage you need, then you can use a transformer to make the change. (But that only works for AC.) -- You can use a transformer to change the output impedance of an amplifier to the impedance of the speaker or earbuds you want to use with it.
How can you identify which one is step up or step down transformer?
A transformer has two windings, termed the 'primary winding' and the 'secondary winding'. The primary winding is the winding connected to the supply, while the secondary winding is connected to the load. The secondary voltage of a 'step up' transformer is higher than the primary voltage; the secondary voltage of a 'step down' transformer is lower than the primary voltage. The simplest way to determine whether a transformer is a step up or step down, is to measure the primary and secondary voltages. If you are simply looking at a transformer, then the transformer's insulated bushings will give you a clue -the higher voltage bushings are much bigger than the lower voltage bushings. If you have access to the inside of the transformer, then the higher voltage windings are thinner and have a greater number of turns than the lower-voltage winding.

How do you test a stick welder transformer?
This could be dangerous if you aren't very careful. Take the transformer out of the welding machine. Put it on a wooden bench. Apply 12 volts to the input side with a car battery. Measure the input volts with a volt meter and write down the value. Then use your volt meter to measure the output voltage. If you have no output voltage then your transformer is obviously blown. You should read an output voltage that is higher than the input voltage based on the number of winding in the coil and/or the manufacturers specifications. According to Faraday's law the only output voltage you will read is at the exact time power is applied to or taken away from the input when using dc power. Otherwise you will have to apply ac power which is much more powerful ( and more dangerous ) than the 12v dc. Your volt meter may not be designed to read high enough voltage for the output you would see with 110 v ac.
How much lm317t ic can bear voltages?
The LM317 voltage regulator can be set to any output voltage from 1.2 V to 37 V. You must keep the input voltage between the maximum input voltage and the drop-out voltage for proper operation. The maximum input voltage the LM317 is guaranteed to bear is 40 V. The LM317 is guaranteed to operate when the input voltage is at least 3 volts above the set output voltage.

Difference between voltage transformer and capacitive voltage transformer?
A capacitor voltage transformer (CVT) is a transformer used in power systems to step down extra high voltage signals and provide a low voltage signal, for measurement or to operate a protective relay. Inductive voltage transformers use conventional magnetic material for coupling of HV and LV circuit. This method has problems due to insulation of EHV circuit to the magnetic core( usually at ground potential) and very expensive to produce as it may need a few step down stages to achieve to final voltage ratio, each stage shall be floated at gradually reducedvoltage relative to ground potential.
What is meant by the term small signal amplifier?
Small signal amplifiers are generally referred to as "Voltage" amplifiers as they convert a small input voltage into a much larger output voltage.
When a PNP transistor is connected in certain circuit manner it can be used as a power amplifier because?
not sure if this is the answer : the output voltage will be much larger than the input voltage.
Does an isolation transformer work from 50 Hz input to 60 Hz output?
Generally speaking, an isolation transformer will work pretty much the same for 50 Hertz as for 60 Hertz. There will be some slight differences, but the frequency is low enough and the the range narrow enough that the transformer will just "do its thing" regardless. Note that the isolation transformer won't change the frequency of the input. An input of 50 Hz or 60 Hz will yield an output of 50 Hz and 60 Hz respectively. No change should be expected.
What are transformer used for?
Transformers change the numbers of volts, watts, and amperes of the electrical current, from those in the power source to those needed for the mechanism. Generally, transformers are used to change the input voltage to a desired value of output voltage. Typically, transformers step up (increase) the voltage, or step down (decrease) the voltage. There are many applications and uses for transformers - most of these embed the transformer in another device, so you do not see (or even know about) the transformer. A computer power supply, for example, has a transformer embedded in it that converts the incoming 120 volts into both 12 and 5 volts. As another example, when travelling from North America to Europe, travelers often take with them an adapter that includes a step-down transformer that converts the European 220 volts into the 120 volts that the North American appliances require. Note that the transformer cannot change the frequency of alternating current, and so some 60 Hz North American appliances will not work properly in Europe, even with a proper step-down transformer, because European power is distributed at 50 Hz. Similarly, some 50 Hz European appliances will not work properly with 60 Hz North America power, even with a proper step-up transformer. Transformers are also included in adapters for electronics, such as for a cell phone charger. A transformer inside the adapter reduces the incoming 120 volts into a lower voltage (sometimes, 3, 5, 6, 9, 12 or some other value of volts) that the cell phone can accommodate. Such electronic adapters (and the computer power supply, noted in the example above) often include a rectifier that also converts the alternating current (AC) into direct current (DC), which reduces peak-to-peak voltage without affecting RMS (root mean square) voltage. Most transformers have fixed ratios, meaning the output voltage is always a constant fraction of the input voltage. The output of these fixed ratio transformers will fluctuate in proportion to the fluctuation of the input voltage. Some transformers are variable ratio, meaning you can adjust (either manually or automatically) the ratio of output to input voltages. Automatic variable ratio transformers are typically used to output a constant voltage, regardless of how much the input voltage fluctuates. Also to destroy the decepticons.
