schematic drawings explain electrical circuits. First you must know the basic requirments for any curcuit.

1. All circuits must do work. ( without a load the wiring becomes the load and it burns up. This is known as a short circuit.

2. All circuits must have an electrical path. From a voltage sourse to a load and back to the source.

3. There must be a way to control the electrical force. for example to turn it on and off.

When looking at schematics there are essential questions you should ask yourself. What is the intent of the circuit? How is it controlled? Where is the load? What is the load? Where is/are the controlling switches...etc? Is the contol voltage the same as the load voltage? What coil controls what contacts?

Schematics are often laid out as ladder diagrams. These show each simple circuit one at a time. IF they are now laid out a ladder diagrams many find it useful to redraw the schematics to put them in that form.

Schematics use symbols it represent different parts of the circuit. Often circles will denote a coil portion of a relay (or automatic switch) Often there will be a letter in the circle to identify the coil. That letter will also be assigned to sets of contacts that that coil operates. Contacts can be NO normally open or NC normally closed. Normally closed means that there is an electrical path across the contacts when the coil is not energized. Normally open means that the switch is off or there is no electrical path across the switch when the controlling coil is not energized.

This is a long subject and I will add to it from time to time. and any who know the subject are invited to add information to this answer as they wish.

What is the drawing of an electrical circuit called?

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.

What is electrical schematic of 2004 Chrysler Concorde?

An electrical schematic diagram, shows where the wires and conductors connect to components. It is not a literal layout and is expanded to make it easier to read and understand. The wires do not neccessarily follow the same path in the diagram, but the end results are the same. In a schematic diagram for a car, the colours of the wires are also noted, so that they can be traced and identified.
