Depending on your application... Use a voltage dividor (two resistors) if it doesn't draw a lot of current. You could also try a voltage regulator or using an op amp as a buffer, with the input the voltage you want. That voltage could come from a voltage divider, since op amps draw extremely low current.
A transformer is a device that raises voltage by using electromagnetic induction to transfer energy from one circuit to another. Transformers can step up or step down voltage levels depending on the ratio of turns in the primary and secondary coils.
A transformer is the obvious answer, however there are other devices, like Jacobs Ladders, inverters, buck-boost circuits, and not to forget the SEPIC circuit. (Google that.)

What is the name of the device that changes the voltage?
A transformer is a device that changes the voltage of an electrical current, either increasing or decreasing it depending on the design.
What necessary condition must a voltage measuring device satisfy?
A voltage measuring device must have a high input impedance to prevent loading effects on the circuit being measured. This ensures accurate voltage readings without affecting the circuit's behavior.
What is relation between voltage and temp?
The relationship between voltage and temperature can vary based on the material or device in question. In general, an increase in temperature can lead to an increase in resistance, which in turn can affect the voltage drop across a circuit. It is important to consider the specific characteristics of the material or device when analyzing the relationship between voltage and temperature.
How to find resistance?
To find resistance, you can use Ohm's Law, which states that resistance (R) is equal to the voltage (V) divided by the current (I). Mathematically, R = V/I. Alternatively, you can use a multimeter to directly measure the resistance of a component or circuit.
What is the device that detects electric charges?
An electrometer is a device that detects electric charges by measuring the voltage or current associated with the charges.
What device raises or moves fluids?
A pump
What device is also called a rectifier?
A rectifier is an electronic device that changes an AC voltage to a DC voltage.
What is mean by thresold voltage?
the device oprates on the minimum voltage. in this voltage is called threshold voltage.
Difference between Threshold voltage and knee voltage?
the voltage at which electronic device operates is callled threshold voltageand the voltage at which device show cinduction in forward biased stste
What will happen if you use phase to phase voltage for a single phase device?
If a single-phase device is connected to a phase-to-phase voltage, the device may get damaged due to the higher voltage applied. Single-phase devices are designed to operate at a lower voltage compared to phase-to-phase voltage levels typically found in three-phase systems. It is important to match the voltage ratings of the device with the supply voltage to prevent damage.
What would be the most effective method to test a broken circuit?
Do a voltage test. Start at one end of the circuit and progress along device by device. If there is voltage on the down stream side of the device move on to the next. If there is no voltage on the down stream side of the device then go up stream of the device. If you have voltage there then the current device that you are at is the problem causing an open or broken circuit.
What is the Difference between voltage controlled device and current controlled device?
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.
Can you use a 12v power adapter when device requires 6v?
No, twice the voltage applied to a device that only requires 6 volts will probably destroy the device. When a manufacturer of equipment states a required voltage for a device that is the voltage that must be used.
What is voltage stabilizer?
Voltage stabilizer is use to regulate the voltage the output of any device
How can you change dc voltage into ac voltage?
The device to do that is called an inverter.
Will a 9v DC adapter damage a device that requires a 6v DC adapter?
Yes, the manufacturer specifies what the working voltage of a device will be and that voltage has to be adhered to.
What device increases the voltage?
watts
