The ground symbol looks like an arrow pointing down, but the point of the arrow is drawn with individual lines to make it stand out from other arrows used in electrical diagrams, like the digital or common ground arrow.

The resister symbol represents an area or piece that is restricting the flow of current. The symbol looks like a jagged or wavy line. Resistors are normally used in conjunction with capacitors. This duo will be found generally in a timing circuit.

The generator symbol is a power source symbol. The voltage in the area indicated with the generator symbol is created by an actual generator, which may be set up outside or in a basement. The symbol is the letter G in a circle with two lines coming out of each side.

There are numerous power supply symbols because of the different types of power and different types of power current. These symbols can help prevent injuries or incorrect wiring, especially if there is a crew of electricians or construction workers in one area working on various elements of the construction.
