THE ART OF DRAWING
FIGURES & CIRCUITS
Figures & Circuits can talk to
us, more than words…!
Vidyasagar Sir explains…
FIGURES CAN TALK TO US…!
Anyone can draw figures, but not
NEAT AND CLEAN.
Very few students can draw figures TO
Even a few of them can draw figures
with correct orientation.
Drawing a perfect figure is an art!
HOW TO LEARN THIS ART?
Keen observation is THE KEY to
acquire this art.
When your teacher draws a figure on
blackboard, it is NOT your free time to
chat with your friends.
Instead, you must concentrate; how is
he drawing it?
WHAT TO OBSERVE?
Observe each and every action of the
From where does he start?
What are the movements of his hand? How does
he draw curves?
How does he connect one component with the
What are the size proportions of one component
with the other?
Which component in the figure is distinct than
The list could be, just endless…!
It’s up to you, how do you watch it and keep
it, in your mind…!
Most importantly, HOW DO YOU TRY IT FOR
Try it for sure…! It’s simple…!
You, too, can do it…!
Your teacher was also a student. But he
cultivated this art, with practice, practice and
You know it. Practice makes a man perfect…!
HOW TO ACQUIRE THIS SKILL?
I told you already. It’s a matter of
observations & practice!
So! Are you ready to learn it…?
I knew, you are a smart student…!
First know the basic things…
There are 3 styles of drawing a figure or a
circuit on a paper or even in the answer
The left aligned figure.
The right aligned figure.
And the centered figure.
While drawing figures in Physics, Chemistry
or Electronics Exams, it is better to draw
LEFT/RIGHT ALIGNED FIGURE
These are left & right aligned
figures, with some text surrounding
it. They are generally small figures
and have not long description. Such
figures are better to align either
left or right.
These figures have one drawback.
While reading the text, sometimes
they may be overlooked!
CENTER ALIGN FIGURE
Following circuit is center aligned. Because its
horizontal expanse is more than vertical height…
This circuit has long description. It’s working is also
related to wave diagrams and truth table, etc.
So such figures must be center aligned.
Symbols of battery & capacitor are
Indicate input/output terminals of a
block or circuit with hollow circles.
Wires connecting each other are marked with a thick dot.
And the wires crossing but not connecting have no dot.
Every component, block, device, label, etc. must be
proportional with respect to each other.
Symmetrical circuits look beautiful & create good
impression on the mind of a teacher…!
Don’t draw any symbol in two different ways i.e.
always use same symbol for same device.
A detailed labeled figure can directly “talk” with
This is a stand alone figure. The figure itself explains the
process and mechanism of CRO display. But such figures are of
course difficult to draw. However, you must try.
Don’t be afraid to leave blank areas on the page
but don’t try to fill up the page, either.
All wires must be aligned either vertically or horizontally,
unless there is a good reason to do otherwise.
All parts must have a label and distinct &
informative caption to the circuit...
The direction of current in the circuit must be
correctly shown. KCL must be understood clearly.
Instead of joining number of lines together, you can
break the connections and simplify the look of the
While drawing a wave and its details, its shape must be
Its relevant quadrant and projections on the axis must
be clearly shown.
Every symbol must represent the exact identity of
the relevant device…
When a circuit has two different sets of working, it’s
a good idea to draw two independent circuits with
If you want to draw the schematic of a device, be
careful about its real shape & appearance to project
its 3D view…
But if you want to draw just 2D schematic, you can
ignore the inner details...
Proportion is a vital element in figures, when it
comes to waves in particular...!
Size, shape, symmetry and proportion are very
important factors, while drawing logic circuits...
Specific arrangement, order
of repetitive connections,
distinct internal spacing
and relevant proportions
makes the circuit beautiful
as well as easy to
But sometimes, in special cases, you have to ignore
proportions to manifest the meaning of figure…
Shading the important sections of a figure, creates
good impression and also become noticeable…
Showing directions with arrows is also an important
element through which the student can convince
the teacher, that his concepts are clear…
Sometimes, to manifest a crystal clear concept in
the form of an idea, a box creates beautiful impact
on the mind of a reader...!
No matter that the neat
and clear figures or
circuits or diagrams ,
create good impression...
But sometimes the
also creates very good
impression on teacher...
WELL, WELL, WELL…!
My dear students, these are just the tips with which
you can improve your figures and circuits and
diagrams while writing in the ANSWER SHEET in
Remember, you may be already well prepared in
your subject, but...
The presentation makes
all the difference…!
A ruled paper of average size.
A soft support to hold below the paper.
A pen or pencil
A small 6” scale,
if you’re not sure,
you can draw
a straight line…!
This slide show is written for the
students who draw electrical &
electronic circuits. But hope that, it may
be equally helpful for other students,
