The polarity of a DC output from a power supply is determined by the arrangement of the internal components, such as diodes and Transformers, as well as the direction of current flow. In a typical power supply, the positive terminal is connected to the anode of the rectifying diodes, while the negative terminal connects to the cathode. Additionally, the design of the power supply circuitry, including whether it uses a single-ended or dual-ended configuration, also influences the output polarity.
AC source of electric power changes changes polarity constantly, in amplitude.
Yes.
The input voltage range for the Toshiba power supply is AC 100V - 240V. The output voltage is DC 19V / output current is 4.74A. This power supply comes with a power cord and packaging will state voltage recommended for the product.
A variable power supply is one whose output voltage (or current) can be adjusted and therefore set to a desired figure. They are used in development and design odf circuits, eliminating the need for possibly many power supplies of different output voltages. Once a circuit is connected to it, the output would not normally be changed.
There is no answer to this. If a power supply pulsates, what frequency, etc. If a power output needs filtering there are oodles of ways to do it depending on the desired result and the starting conditions. A starting point is a big capacitor.
Power supply units are rated based on their output and efficiency. When more equipment is connected, a higher output power supply is needed.
????????????????
Output - because it is outputting power to the rest of the device

Obtain a power supply that has the correct output voltage that you need.
Yes.
because it is devices
Watts.

Case form factor determines the physical size of a power supply and the placement of a screw holes. It can be ATX, microATX, BTX and others.
The "power supply" supplies power to a computer. A computer's power supply is a "switchmode power supply" responsible for converting the AC voltage from the wall into several DC output voltages.
Yes. Depending on the design, the power supply can provide any voltage desired.
