To make things simpler! Imagine if they had to draw an actual transistor or battery everytime... that would have been both time consuming and difficult for the person studying the diagram ( as one engineer's drawing of a transistor may be totally different from others )
Wikipedia has one under "Adder". I apologize, it is not easy to draw such things here.
There is a short circuit somewhere in the electrical system.
Hmm, lets see; 1. closed 2. energized 3. a load(something drawing power, ie. light bulb)
According to ohms law... V=I * R So from the given values V = 4.3*16 = 68.8 Volts
The drawing of an electrical circuit is called a.............= schematic drawing.
schematic drawing
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.

The study/ art of drawing or making diagrams
If one takes a look at the schematic drawing of an auto-retract clamp and drill hydraulic circuit, one will see the single-acting clamp cylinder and quarter of an inch operator control valve. It also has double-acting work cylinder, as well as quarter inch air sequence valve.
The term "schematic" comes from the greek word "schema" which means "drawing".
schematic
Schematic or drawing showing the layout of components.
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.
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.
