Lesson 0: Section 2: Voltage, Current, Resistance, Power ... from www.circuitmason.com

Power is like the volume of water that isflowing from the hose, given a specific pressure and diameter. In a mechanical system, input and output are force and velocity respectively. We don’t know, and at this point, we don’t care.

If the positive terminal is connected to, say, the output port of an operating pump, and the negative terminal is not connected to an.

The water analogy breaks down a little here but ac is easily created by electric generators (also called alternators). Batteries can be thought of as water pumps that circulate water through a hose that travels in a closed loop back to the battery. Voltage can be as negative as necessary to satisfy the physical laws of electricity. For all practical purposes, enough of the gas molecules can be removed so that a practical perfect vacuum can be achieved, and absolute pressure instruments can be built.
