What device raises voltage?

Answer 1

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.

Answer 2

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.

Answer 3

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.)

Answer 4

A step-up transformer

Answer 5

Transformer.

Answer 6
