What else can I help you with?
Can you use a step down transformer as a step up transformer by reversing the secondary voltage as a primary voltage?
Yes a Tesla coil or ignition coil is an example.
What is meant by a primary coil and a secondary coil?
In a transformer, the primary coil is the coil that has voltage applied to it. The secondary coil is the coil that we take voltage from. Transformers are used to step up voltage, step down voltage, or simply to isolate circuits.
What is difference betweena step up transformer and step down transformer?
The difference between the two transformers is the coil ratios between the primary and secondary windings. A transformer that increases voltage from primary to secondary has more secondary winding turns than primary winding turns and is called a step-up transformer. Conversely, a transformer with fewer secondary windings does just the opposite and is called a step-down transformer.
What type of transformers are used to step down a voltage for general use and what type of systems are they classified as?
The transformer you describe is being used as a step-down transformer, and is classified as an electrical machine. The transformer could either be a mutual transformer, consisting of two, electrically-isolated coils, or an auto-transformer which uses a common coil between its primary and secondary circuits.
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 is a transformer called that increases voltage?
A transformer that increases voltage is a step-up transformer.

In a transformer, the primary coil is the coil that has voltage applied to it. The secondary coil is the coil that we take voltage from. Transformers are used to step up voltage, step down voltage, or simply to isolate circuits.

Why is the number of turns in primary coil more than that of the secondary coil?
The number of turns or windings of a transformer can vary. There can be more in the primary, or more in the secondary, or there can be an equal number in a transformer that is simply used for isolation (an isoformer). More turns in the primary than secondary will create a step down transformer. More turns in the secondary are found in a step up transformer. The transformers on power poles have more turns in the primary to step the line voltage down for delivery to residential customers.
A step-up transformer has 300 turns on the primary coil and 90000 turns on the secondary coil if the current flowing through the secondary is 5 amps what is the current flowing in the primary?
If a step-up transformer has 200 turns on the primary coil and 3000 turns on the secondary coil, with a primary coil voltage of 90 volts and current of 30 amps, then the turns ratio is 200:3000, so the secondary voltage is 1350 voltage and the available current is 2 amps. (This ignores losses through the transformer.)
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.
What is the difference between a secondary and primary coil?
The primary coil is the one with voltage applied, or the 'input'. The secondary coil is the one in which a voltage is induced by electromagnetism, or the 'output'. In a step up transformer, the secondary coil voltage is higher than the primary. In a step down transformer, the secondary coil voltage is lower than the primary. In an isolation transformer, the secondary coil voltage is the same as the primary. Here, the point of the transformer isn't to raise or lower voltage, but to keep a particular circuit electrically disconnected from another circuit, while still allowing the circuits to function together (through electromagnetism).
What are step up transformers?
A transformer is a device that changes (transforms) and alternating potential difference (voltage) from one value to another value be it smaller or greater using the principle of electromagnetic induction. <a class="h2heading h2" style="color: rgb(0, 0, 0);" name="Step-up Transformer:">Step-up Transformer:</a> On a step-up transformer there are more turns on the secondary coil than the primary coil. The induced voltage across the secondary coil is greater than the applied voltage across the primary coil or in other words the voltage has been "stepped-up."
What does a step up transformer do to increase the voltage of an electrical current?
A step-up transformer increases the voltage of an electrical current by having more turns in the secondary coil than in the primary coil. This causes the magnetic field to induce a higher voltage in the secondary coil, resulting in an increase in voltage.
A step-up transformer has 300 turns on its primary coil and 90000 turns on its secondary coil If the current is flowing through the secondary is 5 amps what is the current flowing in the primary?
150 amperesAnswerYour transformer's primary current will be:Is = Ip (Ns/Np) = 5 (90 000/300) = 5 x 300 = 1500 A
. A step-up transformer has a primary coil with 100 turns and a secondary coil with 25 turns. If the input voltage in the primary coil is 40 volts what is the output voltage reduced to in the secondar?
The output voltage in the secondary coil would be increased. Using the transformer formula Vp/Vs = Np/Ns (where Vp = primary voltage, Vs = secondary voltage, Np = number of turns in primary coil, Ns = number of turns in secondary coil), we can calculate the output voltage to be 160 volts (40V * 100/25).
