An external power supply is a separate device used to provide electrical power to another device, such as a laptop or phone. It typically consists of a power cord and an adapter that connects to the device needing power. This type of setup is commonly used for charging devices or providing power when the internal battery is low or unavailable.

The electrons that flow through a circuit come from the power source, such as a battery or generator. When the circuit is closed, the power source creates a potential difference that drives the flow of electrons through the circuit.
You can measure the current and power of a 'power supply', using an ammeter and a wattmeter. With the power supply connected to its load, the ammeter must be connected in series with the power supply's input. The wattmeter's current coil must also be connected in series with the power supply's input, and its voltage coil must be connected in parallel with the supply, taking the instrument's polarity markings into account.
When sunlight hits the solar panel, the photons in the light excite the electrons in the panel's semiconductor material, causing them to move and create an electric current. This flow of electrons generates electricity that can be used to power devices connected to the solar panel.
Electrons in the cathode do not end up because they are continuously being replenished by the power source connected to the cathode. This power source provides the necessary energy to liberate electrons from the cathode material, ensuring a constant supply of electrons available for emission.
The GameCube's power supply is internal. The whole system is very easy to transport.
An internal power supply is usually a battery. An external power supply means the electric current that you get by plugging your device into a wall outlet. If you do not have to plug it in, then it has its own power supply inside the actual device, in other words, it is internal. Aside from a battery, it could have photovoltaic cells to generate power, or other internal sources of power, anything other than an external source.

A USB hard disks that does not require a power supply is powered by your computer via the USB connection. Where as others require an external power supply because of the amount of power they require. It is usually a "wall wart" type that plugs in to your wall socket with a lead that plugs in to the disk drive.

All computers have an internal power supply... An external one is simply for back up if you lose power.
smps is a switch mode power supply
An example of a passive transducer is differential transformers. The reason why is because passive transducers require an external power supply to operate.
Yes. If the power supply is of a low wattage and has too many pieces of hardware connected to it, it can. Try buying a power supply with a wattage over 300. One thing to check before replacing the power supply is the voltage selector in the back. If you use 120 volt power, then setting the power supply to 240 volts will cause the PC to only get half of the power it needs. External peripherals with their own power supply will not impact the power supply or current in the computer. Printers and monitors usually get their power from the wall socket, not the computer, and the same goes for external modems that plug into the wall. Keyboards and mice take negligible power.
If it's a "clean" power supply with the proper voltage, it shouldn't be a problem.
A laptop runs on DC. Either from the battery, or the external power supply, which converts AC power to DC.
