A circuit diagram (also known as an electrical diagram,
elementary diagram, or electronic schematic) is a
simplified conventional graphical representation of an
electrical circuit.

LED
A light-emitting diode (LED) is
a two-lead semiconductor light
source. It is a p–n junction diode,
which emits light when activated.

LDR

17. by Tajim 17
A capacitor is
a passive two-
terminalelectrical
component that
stores
electrical energy in
an electric field.
The effect of a
capacitor is
known
as capacitance.

18. Transistor
by Tajim
18
A transistor is a semiconductor device used
to amplify or switch electronic signals and
electrical power. It is composed of
semiconductor material usually with at
least three terminals for connection to an
external circuit.

19. Transformer
by Tajim
19
A transformer is an electrical device that
transfers electrical energy between two or
more circuits through electromagnetic
induction. Electromagnetic induction produces
an electromotive force within a conductor
which is exposed to time varying magnetic
fields.

20. IC (integrated circuit)
by Tajim
20
An integrated circuit (IC), sometimes
called a chip or microchip, is a
semiconductor wafer on which
thousands or millions of tiny resistors,
capacitors, and transistors are
fabricated.
An IC can function
as an amplifier,
oscillator, timer,
counter, computer
memory, or
microprocessor.
