What is the difference between a transformer and a rectifer?
A transformer is used to change the value of a voltage applied to the transformer's primary winding to a different voltage value taken from the transformers secondary winding. A rectifier is used to change an alternating current value to a direct current value.
What does a buck boost transformer do?
A buck boost transformer is a type of transformer that is used to make adjustments to the voltage applied to alternating current equipment. These transformers are typically used in back up supplies or in tanning beds.
What is construction and working of single phase transformer?
The single phase transformer works on the principle of mutual induction. Explanation: When an alternating voltage V1 is applied to a primary winding, an an alternating current I1 flows in it producing an alternating flux in the core. As per Faraday's law of electromagnetic induction, an emf e1 is induced in the primary winding. Where N1 is the number of the turns in the primary winding's induced emf in the primary winding is nearly equal and opposite to the applied voltage V1
When an alternating voltage is applied to purely resistive circuit what happens?
When an alternating voltage is applied to a purely resistive circuit, the resulting current is in phase with the voltage.
Ac voltage applied across a load resistance produce alternating current?
The reason an AC voltage applied across a load resistance produces alternating current is because when you have AC voltage you have to have AC current. If DC voltage is applied, DC current is produced.

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.
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 is the science behind the alternating current?
When a sinusoidal alternating voltage is applied in a circuit, the resulting alternating current is also sinusoidal and has the same frequency as that of applied voltage .However, there is generally a phase difference between the applied voltage and the resulting current.This is how alternating-current circuit works.

What do you nned to make an electric current?
An electrical potential difference (aka. a difference in applied voltage), and a conductor / circuit. Electrons would help too.
If 110 V ac is applied to the primary what is the output potential difference?
This answer should contain the amount of turns that the primary and secoundary have.
Ac voltage applied across a load resistance produce alternating current?
The reason an AC voltage applied across a load resistance produces alternating current is because when you have AC voltage you have to have AC current. If DC voltage is applied, DC current is produced.
Dielectric constant of insulator depends on?
Frequency of alternating field applied & temperature
What is the difference between potential energy and potential difference?
The term potential energy is applied to the energy a thing or material has because of its nature or position. Things can have potential energy because they are at an elevated point in a gravimetric field. There are types of mechanical potential energy like that held in a spring. Things or materials can also have potential energy because of their chemical, electromagnetic or nuclear characteristics. The term potential difference is applied to compare two things or substances, or points in a system (like an electrical circuit) that are at different potentials. A roller coaster at the top of the "starting grade" will have a greater potential energy (positional energy owing to gravity) than one at the end of its run. A chemical explosive has a higher chemical potential than the chemical components used to make it.
