The document discusses drawing circuit diagrams using standardized symbols to represent circuit components. It explains that a universal system called a schematic diagram has been developed to allow people to understand circuit diagrams. Examples are given of drawing schematic diagrams to represent physical circuits using the proper symbols and order of components. Readers are prompted to practice drawing their own schematic diagrams from pictures of circuits.

1. Drawing Electric Circuits

2. Drawing Circuits
It is often necessary to draw a circuit to let another
person know what it is supposed to look like.

3. Drawing Circuits
Since everyone has their own ways of drawing pictures, a
universal system for drawing circuits has been developed.

4. Drawing Circuits
This system consists of many different symbols that can
be connected like puzzle pieces.

5. Drawing Circuits
This system consists of many different symbols that can
be connected like puzzle pieces.

6. Drawing Circuits
The universal way of drawing circuits
is called a schematic circuit diagram.
We have already seen several of
the symbols that are used.

7. Try This.
Draw the schematic circuit diagram of this circuit picture:

8. Try This.
Answer:
or
Rotation of the whole circuit or the amount of connector do
not matter – but try to use only as much connector as
required to make the diagram look neat.

9. Try This.
Draw the schematic circuit diagram of this circuit picture:

10. Try This.
Answer:
Connecter lines must be straight.

11. Try This.
Draw the schematic circuit diagram of this circuit picture:

12. Try This.
This is incorrect.

13. Try This.
Answer:
Getting the order of components correct is important.

14. Try This.
Draw a circuit with a source that leads out the negative end
into a light bulb, followed by an open switch, a
motor, another light bulb, a resistor, and then back into the
source.

15. Try This.
Draw a circuit with a source that leads out the negative end
into a light bulb, followed by an open switch, a
motor, another light bulb, a resistor, and then back into the
source.
