# What Is An Electrical Schematic Drawing

An electrical schematic drawing is a diagram that shows the electrical components of a circuit and how they are connected. It is used by electrical engineers to design and troubleshoot electrical systems.

Electrical schematic drawings are typically drawn using a standardized set of symbols to represent different electrical components. These symbols are defined by the International Electrotechnical Commission (IEC).

The symbols used in electrical schematic drawings can be divided into two main categories:

*

### Device symbols:

These symbols represent individual electrical components, such as resistors, capacitors, inductors, and transistors. *

### Connection symbols:

These symbols represent the connections between electrical components.

Electrical schematic drawings are typically drawn in a top-down view, with the positive terminal of the power source at the top of the drawing and the negative terminal at the bottom. The components of the circuit are then drawn in a logical order, with the power source connected to the load.

Electrical schematic drawings are an essential tool for electrical engineers. They allow engineers to visualize the electrical system and to troubleshoot problems. By understanding the electrical schematic, engineers can identify potential problems and make necessary repairs.

Here is an example of an electrical schematic drawing for a simple circuit:

This schematic drawing shows a simple circuit that consists of a battery, a resistor, and a light bulb. The battery provides the power for the circuit, and the resistor limits the flow of current to the light bulb. The light bulb then converts the electrical energy into light energy.
