increase power

[khushbu0694]

actually i was asked this question:-

what is the name of that equipment which will increase the power, current, voltage without changing the height of the signal?

Might be talking about power-factor correction.

Normally you would call the "height" of the signal its voltage. So if height is not the signal voltage, what is it?
