Q1 of 9 Page 138

Dismantle a defunct radio and try to understand its various parts.


The following is a picture of dismantled radio the parts which are identifiable are :


Capacitor -The function of the capacitor in the radio is to set or change the frequency. It is used to tune up the device for a particular frequency.


Transistor - Sounds are recorded in studios through a microphone and turned into electrical signals. Those signals travel through a circuit, and the transistor amplifies the signal, which is much louder when it reaches a speaker.


Resistor - The resistor controls the amount of electricity which needs to run the whole set up and as well as any particular part.


Diode - Diode is the semiconductor device which is used to control the amount of flow of current in any particular direction.


IC chips - IC chips are the main parts of the radio since they contain all the information on how to work. They are actually a set of rules upon which the device works.


Amplifiers - Amplifiers are the parts which are used to increase the strength of the signal.


Speakers and wires - All the connection is done by wires and speaker are used to convert signal into sound.
