A device that decreases voltage?
Step down transformer, potentiometer or rheostats can all be used to reduce voltage.
What type of device is used to increase or decrease the voltage of an electric current?
The device used to increase or decrease the voltage of an electric circuit is a step up transformer or a step down transformer respectively. A Variable Resistor
What is an adaptor and how is it used?
An adapter, depending on what device your using it for connects that device to the internet or a network.
Why are step-down transformers used?
A step-down transformer is a reverse-wired step-up transformer. You can take a 110/220 transformer and feed 110 to step up to 220 or feed 220 to step down to 110. step down transformer is a device which reduces voltage .
Where might a step-down transformer be used?
Step-down transformer is used at grid substations for feeding various substations which further step down the voltage for feeding distributing transformers and further step down transformers are used to supply the voltage for the consumer uses
A device that decreases voltage?
Step down transformer, potentiometer or rheostats can all be used to reduce voltage.
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.
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
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.
What is the transformer and starter?
A transformer is a static device which is used to step up or step down voltage without changing frequency. A starter is a device used to start the motors.It is used to limit the starting current to a safe value.
Why transistor is not used as a transformer?
transistor is switching device - no converting that input vales transformer is converting like step up/down that in voltage values
What type of device is used to increase or decrease the voltage of an electric current?
The device used to increase or decrease the voltage of an electric circuit is a step up transformer or a step down transformer respectively. A Variable Resistor
What is used to step up or step down the voltage?
Low frequency coils
What is an adaptor and how is it used?
An adapter, depending on what device your using it for connects that device to the internet or a network.
Can stabiliser used in place of transformer?
No, because stabiliser is used to stabilse the voltage level not for step up or step down more voltage.
What is the purpose of transforms?
A transformer is used to step up or step down a Voltage supply.
What is the principle of transformer working Explain the working principle of transformer on no load?
Transformer is a static electrical device used to step up or step down the voltage with the help of primary and secondary windings.
