Today I am going to make an audio amplifier using 3055 Metal Transistor.
Let's get started,
Teachers! Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson.
Step 1: Take All Componenets As Shown Below
Components required -
(1.) Transistor - 3055 x1 (Metal Transistor)
(2.) Capacitor - 25V 100uf x1
(3.) Resistor - 1K x1
(4.) Aux cable
(5.) Battery - 9V
(7.) Battery clipper
Step 2: Transistor - 3055
This picture shows the pinouts of metal transistor 3055.
Step 3: Connect 1K Resistor
Solder 1K Resistor between Base and collector of the Transistor as solder in the picture.
Step 4: Connect Capacitor
Next we have to solder +ve pin of capacitor to Base pin of transistor as you can see in the picture.
Step 5: Connect Aux Cable
Next Solder Left/Right wire of aux cable to -ve pin of capacitor and
Solder GND wire of aux cable to Emmiter pin of the transistor.
Step 6: Connect Speaker Wire
Solder -ve wire of speaker to Collector of 3055 transitor as solder in the picture.
Step 7: Connect Battery Clipper Wire
Now we have to connect battery clipper wire to the circuit.
Solder +ve wire of battery clipper to +ve wire of speaker and
Solder -ve wire of battery clipper to emmiter pin of the transistor as you can see in the picture.
Step 8: Circuit Is Completed
Now our audio amplifier circuit is completed so connect battery to the battery clipper and
Plug-in aux cable to mabile phone and play music.
This type we can make an audio amplifier circuit using 3055 metal transistor.
