3. Reed Switch:

Definition: A source of energy. It contains active materials which are irreversibly converted during the chemical reaction.In physics, one "battery" on its own is called a cell. Two or more cells which are joined together are called a battery.

Batteries can be used for several functions:· Storage: Batteries store energy being produced by a given generating source, and when this source is unavailable this energy can be used by the load· Start- up current: Batteries can provide higher currents to the load than the array alone can provide. Many motors initially have a high current requirement.· Power conditioning: Two cases where this feature is used in directly coupled systems, such as water pumping, and in uninterruptable power supplies.

A device for opening and closing power source to a circuit

SPST = Single Pole, Single Throw. An on-off switch allows current to flow only when it is in the closed (on) position.

It directs the flow of electrical or optical signals from one side to the other.

A magnetic controlled switch device that opens and closed a circuitA reed switch consists of two ferromagnetic and specially shaped contact blades (reeds) positioned in a hermetically sealed glass tube with a gap between them and in a protective atmosphere. Reed switches are available as form A (normally open) and form C (changeover), and are operated using a magnetic field generated by either a permanent magnet or current-carrying coil.

4. Resistor:

Uses and function:Some common applications of reed switches are: -Reed relays, automotive sensors, robotics sensors, security sensors and toys and games.

· A resistor is a component of an electrical circuit that resists the flow of electrical current· A resistor has two terminals across which electricity must pass, and is designed to drop the

voltage of the current as it flows from one terminal to the next.· Resistance is measured in ohms ( )· The physical size of a resistor also varies dependant on the amount of power passing

through the resistor, given by:

· P = V x I (Power = Voltage x Current) (power measured in watts)

Uses and Functions:

The resistor's function is to reduce the flow of electric current

5. Resistance:

· It is a Measurement of the amount of a device opposes on an electric current through it.

· Ohms Law: R = V / I (Resistance = Voltage / Current) (resistance measured in ohms), where: Voltage [V] = the energy lost across an component (voltage measured in volts).Current [I] = the charge (electrons) flowing through an component (current measured in Amps)

· The resistance value is displayed using the color code (the colored bars/the colored stripes), because the average resistor is too small to have the value printed on it with numbers.Symbol: Resistance measured in ohms, symbolized by the letter "R".

It oppose to the flow of electric current;

6. Variable Resistor:

Symbol:

Uses and functions:

7. Diode:

Symbol:

A kind of Resistor whose value can be changed by tuning the shaft in a electrical circuit.

Variable Resistors usually used to control current. Examples include: adjusting lamp brightness, adjusting motor speed, Volume control and adjusting the rate of flow of charge into a capacitor in a timing circuit.

A device which is use in electric circuit to allows an electric current to flow in single direction and block in the reverse direction.

Uses and Function:

The main function of a diode is to block the current in one direction, and allow current to flow in the other direction. Current flowing through the diode is called forward current.

8. Amplifier:

A device which takes a weak electric signal and sends out a stronger one. Amplifiers are used to boost electrical signals in many electronic devices, including radios, televisions, and telephones

Symbol:

Amplifiers are used in the following fields:

· Military Integrated Assemblies

· Frequency Converters

· Switched Amplifiers

· TTL-Controlled Functions

· Amplifier Filter Assemblies

· High-Density Packaging

A device which is used in electric circuit to allow an electric current to flow in single direction and back it in the reverse direction.

Uses and functions:

Diodes allow electricity to flow in only one direction. The arrow of the circuit symbol shows the direction in which the current can flow. Diodes are the electrical version of a valve and early diodes were actually called valves.

A photoresistor or LDR is an electronic component whose resistance decreases with increasing incident light intensity. It can also be referred to as a light-dependent resistor (LDR), photoconductor, or photocell.

Or

Uses and Function:

? They are generally used in camera, light meters, clock radios, security alarms, street lights and outdoor clocks.

? They are also used in some dynamic compressors together with a small incandescent lamp or light emitting diode to control gain reduction

–A display device which is common used in electronic circuit or equipment as decimal numeric display or indicator.

Uses and Function:

? Seven-segment displays are commonly used by school children to form words and phrases using a technique known as "calculator spelling".

? They are also use an array of light-emitting diodes, Dot matrix.

A capacitor is an electrical/electronic device that can store energy in the electric field between a pair of conductors (called "plates"). The process of storing energy in the capacitor is known as "charging", and involves electric charges of equal magnitude, but opposite polarity, building up on each plate.

Uses and Functions:

· Capacitors are often used in electrical circuit and electronic circuits as energy-storage devices.

· They can also be used to differentiate between high-frequency and low-frequency signals. This property makes them useful in electronic filters.

Ensure all wires are correctly connected to the numbered spring

terminals of the main circuit board unit as stated wiring sequence of

each experiment. Bend the spring terminal over and insert the exposed

shiny conductor part of wire into spring terminal. Make sure the wire

is securely connected to spring terminal.

For example if the wiring sequence is 4-33, 1-10-32-35, 2-12, then

connect a wire between spring terminal 4 and 33; and then connect

a wire between spring terminal 1 and 10, and a wire between spring

terminal 10 and 32, and a wire between spring terminal 32 and 35;

and finally connect a wire between spring terminal 2 and 12. This is

an example for reference only, not an exact circuit connection in the

experiment.

If the circuit does not work, you can check the wire and spring terminal

connection whether it is not well connected or insulated plastic part of

the wire is inserted to spring terminal.

Complete all wiring connections as indicated in the sequence. Switch on the main switch. Small red LED will light up. Current flows from the diode will charge thecapacitor at the same time. When you press the push switch, the large red LED will light up. Release the push switch so that large red LED will be turned off.Now switch off the main switch. The small red LED will extinguish. However if you press the push switch at this time, the

time period, the fan will start to spin. This delay is due to the charging of the capacitor.

During the charging, the base electrode of the triode is in a low voltage so that the triode

is shut. When the capacitor is charged fully, the triode is in its conducting condition, thus

the fan will spin. The time-delay period is the duration of the charging.

NOTE: Every time when you perform this experiment once, remember to “discharge” the capacitor before doing it

again. Otherwise it won’t work properly. To “discharge”, connect any wire to 31-32 for a second. This way the

•

electricity stored in the capacitor will be “discharged” and then the experiment can work properly again.
