In a transformer, you increase or decrease the voltage by changing the turns ratio between the primary or secondary windings. Increase the turns on primary, and secondary voltage goes down. Increase the turns on secondary, and secondary voltage goes up.
Note that this usually involves choosing a different transformer, as changing the turns ratio is not something that can be easily done in the field. Some Transformers have multiple taps on one of the windings which can be used to change turns ratio.

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
Does transformer doubles the power?
No. Power is constant. Transformers neither increase nor decrease power, except for minor losses. They increase or decrease voltage, and they decrease or increase current, but the product of voltage and current, i.e. power, remains the same.
What type of device is used to increase or decrease the voltage of an electric current-?
In an alternating current circuit the voltage can be stepped up ordown efficiently with a transformer.
What device is used to increase or decrease the voltage of an alternating current?
A transformer is the device used to increase or decrease the voltage of alternating current (AC) This is done through a process referred to as inducing.It's operation is based on the fact that electricity produces a magnetic field around itself. By placing 2 coils of cable beside each other, the magnetic field of one coil will induce a voltage in the other coil.
How do transformers reduce electrical voltage?
This type of transformer is called a Step-Down transformer. All transformers have an input to output ratio. The transformers that increase voltage are called Step-up, and the transformers that protect against surges are called unity gain. The Unity gain transformer has a 1:1 ratio and provide a mechanical way to isolate a source of voltage from a load.
What is the name of the component that is used to increase or decrease alternating voltage?
A transformer is used to increase or decrease alternating voltage.
How do you increase the amount of current created by a generator?
You can use a transformer to increase the current. Note that this will also decrease the voltage. The total energy will not increase; it will decrease slightly, due to losses in the transformer.
A transformer can only the voltage of an alternating current?
A transformer can only increase or decrease the voltage of an alternating current, and it is called step-up transformer or step-down transformer accordingly.
Can you increase or decrease an ac voltage?
yes, by stepping it up or down with a transformer.

What is used to increase or decrease voltage that enters a house?
A transformer can be used, either a step-up or step-down transformer, to deliver the power at a different voltage from the normal supply voltage.
What are the two basic uses for a transformer?
To increase or decrease electrical voltage- step up or step down.
What type of device is uses to increase or decrease the voltage of an electric current?
The device is called a "variac' and it is a type of transformer. It has a variable voltage ouput.
How does a stabilizer?
A home voltage stabilizer reduces (buck) or increases (boost) the out put voltage for respective increase and decrease in line voltage. To reduce output voltage the relay cutoff some transformer winding turns, and to increase output voltage the relay add some transformer winding turns in predefined steps.
