Unlike in North America, European three-phase distribution Transformers have star- or wye-connected secondary windings. This provides a three-phase, four-wire, distribution system, comprising three line conductors and a neutral conductor, providing nominal line voltages of 400 V and nominal phase voltages of 230 V.
There are many advantages of electric power over gas power. Electric power does not require fuel to work and electric can be a cleaner source of power.
Advantage of regulated power supply.
Advantages in electric circuits : Advantages of using the rheostat in electric circuits is optional as you could just use the dial on the power-supply to vary the voltage (p.d.), and therefore the current. The advantage of using the rheostat is that you can control it to give you nice even numbers for the voltage.

Advantage of regulated power supply.
To connect the power cord from the power supply to the PS2 power connection on the motherboard, locate the 4-pin connector on the power supply cable and line it up with the corresponding 4-pin PS2 power connection on the motherboard. Gently press and secure the connector into place until it clicks. Ensure the connection is secure and the power cord is properly routed to avoid any interference with other components.
A motor
A: A variable power supply has no disadvantage since it can replace a fix power supply. The disadvantage will rest with the additional cost to make one.
Plentiful supply of water power.
If you lose power the electric motor may supply power.
