The device you are referring to is called a transformer. Not only can a transformer increase voltage, it can decrease voltage as well. These are known as a step up transformer for increasing voltages and step down for decreasing voltages.
A transformer changes the voltage of an alternating current with little loss of energy.
That's called a transformer.
RPS is only the voltage& power controlled device. it can only used for set the input for our wish A device which can change its output according to the voltage supplied to it is called a voltage controlled device.ex. a voltage controlled current source,or a field effect transistor. In a voltage controlled current source the output current changes as the voltage supplied to it changes.
The difference between a current control device and voltage controlled device is that for current controlled device, the current is constant and the voltage is variable while for a voltage controlled device, the voltage is constant and the current is variable.
Triac is the current control device.
A rectifier is an electronic device that changes an AC voltage to a DC voltage.
A transformer.
A transformer is a device that changes the level of an a.c. voltage, while a rectifier is a device that converts alternating current to direct current.
That's called a transformer.
That's called a transformer.
Nothing can change electric current to voltage. You can compare "current " to rate of flow, while "voltage" is the energy level. Transformers can be used to increase or decrease the voltages of alternating current as is done from 'street power' to domestic power.
A rectifier is a device that converts alternating current to direct current. A transformer is a device that changes the ratio fo current to voltage. A rectifier is found in a PC power supply.
In an alternating current circuit the voltage can be stepped up ordown efficiently with a transformer.

A transformer. it steps up / down voltage, and steps down / up current.
