What is the purpose of transforms?
A transformer is used to step up or step down a Voltage supply.
When is a step up transformer used in relationship as to when a step down transformer is used?
If the voltage needs to be increased from a lower voltage to a higher voltage a step up transformer is used. If the voltage needs to be lowered from a higher voltage to a lower voltage a step down transformer is used.
Why transformer is used?
A transformer used to step up or down the value of voltage.
What is the name of the transformer that reduces the voltage?
a step down transformer is used to lower the voltage from the powerlines into your home. a common slang term for this type of transformer is a pole pig.
How do you explain about transformer?
A Transformer is a static device which is used to step up(or)step down the voltage in a transforming conductor
What is the operation of a transformer?
A transformer is a static device which is used to step up or step down the voltage in a powered circuit.
What is Auto transformer and ordinary transformer?
auto transformer is a one winding transformer which is are used for step up and step down voltage without chang its power and friquncy
Uses of transformer?
transformers are used to step up or step down the voltages
What is the difference between a step-up and step-down transformer?
A step-up transformer increases voltage, while a step-down transformer decreases voltage.
Which type of transformer is used in sonometer?
A sonometer is used to determine the frequency of alternating current. A step down transformer is used for the determination of frequency of A.C. because the voltage of the A.C. mains is 220V, which is dangerous. The step down transformer reduces this voltage to 6 volts.
What are the types of and uses for a transformer?
There are two types of transformers:- 1. Step-up transformer & 2. Step-down transformer. A transformer used to increase the voltage is called Step-up transformer. A transformer used to decrease the voltage is called Step-down transformer. Uses of step-up transformer:- in power supply stations, in picture tubes of TV, computer monitors, halogen lights, etc. Uses of step-down transformer:- in supply of electricity to homes, in the power supply to the low voltage devices like radio, music systems which are run by AC mains.
Is ct step up or step down?
'CT' is used to designate current transformers, and 'PT' is used to designate potential transformers. A current transformer provides a ratio of primary current to the secondary. A potential transformer provides a ratio of primary voltage to the secondary. A power transformer (step up or step down) resembles a PT more than a CT.
