Circuit)
2. 1) Understand electronics circuit,
circuit symbol, schematic
diagram and breadboarding;
2) Construct simple electronics
circuit using a breadboard;
3) Value the importance of
breadboarding.
Objectives
3. A particular type of diode that convert
electrical energy into light.
It is a two-lead semiconductor light
source. It is a p–n junction diode,
which emits light when activated.
When a suitable voltage is applied to
the leads, electrons are able to
recombine with electron holes within
the device, releasing energy in the
form of photons.
LED
Light Emitting Diode
(LED)
4. Resistor
- An electrical component that
limits or regulates the flow of
electrical current in an electronic
circuit.
It is a two terminal device have one
connection on each of its sides
5. Light
Dependent
Resistor (LDR)
A resistor whose resistance
decreases with increasing
incident light intensity; they are
used in many consumer
products to determine the
intensity of light.
6. Transistor
a semiconductor device
used to amplify and switch
electronic signals and
electrical power.
It has more than a cell and is
used for the same purpose. The
smaller terminal is negative and
the larger one is positive.
Abbreviated as ‘B’.
Battery
7. Breadboard
- Also called a proto-board, is a
reusable platform for
temporarily built electronic
circuits.
