This question is like asking what is the meaning of life. this needs clarification but...
If you are drawing circuit by hand, for electrical component symbols. you may want to refer to "JIS C 0617" (Google it). These are common symbols used in electrical engineering when defining by looking at what the components are.
If you are drawing by using a PC, there are several free software available when drawing circuit diagrams. It all depends on what your final needs are. If you are just starting off you may want to play with program called "LTSPICE". This will allow you to draw and simulate your design. For more advanced you may want to try program such as "Altium". You will be allowed to draw circuit up to doing the PCB designs.
I hope that helps you to start.
Circuit diagrams, also known as electric diagrams, show the inside of their circuitry. It's mostly used to explain how the basics of circuitry work or how light bulbs light up.

The drawing of an electrical circuit is called a circuit diagram, or schematic diagram. It is a graphical representation of the electrical components and their interconnections in a circuit. It uses standardized symbols to represent different components such as resistors, capacitors, transistors, switches, and wires. The lines connecting the symbols in the diagram indicate the flow of electrical current through the circuit. Circuit diagrams are used to design, troubleshoot, and repair electrical systems, and can be found in technical manuals, books and online resources.
It is often necessary to wire crossing
Yes, pencils exist. They are used for drawing and creating diagrams, and can be erased by a rubber.

Scientists use symbols for diagrams of electrical circuits for a simple reason; to save space. The actuall names of the components would take up immense space on the diagram.
A circuit diagram is used simplified graphical drawing representing an electrical circuit. It shows the actual wire connections using a block diagram or layout diagram. It does not show a physical depiction of the arrangement of components.
Graphing paper is writing paper which is printed with fine lines making a grid. The lines are used for plotting mathematical functions of experimental data and also drawing diagrams.
GFCI's are not used to protect a switch they are used to protect an outlet where something is plugged in.

Do not confuse 'resistance' with 'resistor'. 'Resistance' is a quantity, wheras a 'resistor' is a circuit component. In schematic diagrams, the 'rectangular' (European) or 'zig-zag' (US) circuit symbol represents resistance, not a resistor. The circuit symbol, therefore, is used to represent anyresistive device.
