Basic Electronics

1. Basic Electronics
Introduction

2. -This course deals with the
fundamental concepts of electricity
and electronics. It covers topics on
some passive (resistors, capacitors)
and active (diodes, transistors)
electronic components. It also includes
circuit analysis and troubleshooting
techniques.
Course Description

3. -Also it introduce the students to
some of the frequently used
instruments and equipment like the
multitester and DC Power supply.

7. -are those that have a moving needle that
stops on a number that is printed on the
background behind the moving needle. The
number that the needle stops on indicates
the volts, ohms or amps the meter is
measuring depending on how the control
knob is set.
Analog Multitester

8. Pointer or
Needle –
indicates the
values read
from the scale
Analog Multitester

9. Scale –shows
the value of
what is being
measured
Analog Multitester

10. Dial/Infinity
Knob –points
the needle to
the 0 at the left
side of the scale
Analog Multitester

11. Zero Ohm
Adjuster –
adjusts the
needle to the
right side of the
scale
Analog Multitester

12. Range Selector
Knob –allows
changing the
function and
scale
Analog Multitester

13. Range –allows
more accurate
measurement
for small values
Analog Multitester

14. Test Probes –
Positive probe
(red) and
Negative Probe
(black) are used
to connect to
the circuit or
device under
test.

15. -are those devices that deliver electric power
to one or several loads. They generate the
output power by converting an AC input
signal into a DC output signal.

18. -a rectangular plastic board with a bunch of
tiny holes in it. These holes let you easily
insert electronic components to prototype
(meaning to build and test an early version
of) an electronic circuit.
