It wants Power, not voltage or current. Web8 Mar 2024 · The difference between an op-amp and an amplifier are: 1. Built Up An amplifier is a device that amplifies the input signal. It has three terminals. And the op-amp is a high gain electronic voltage amplifier. It has five terminals. Two inputs, two power supplies, and one output. The output voltage is the difference between the input voltages. 2. WebGoing off of your post content rather than the title, I think you are asking why use higher voltage and lower current vs lower voltage and higher current to drive an equal amount of power. It is often more efficient to use higher voltage and lower current. Wires often have an ampacity rating, which is how much current they are rated to handle. python pyadi-iio
