Introduction: 2222A Transistor Amplifier
Hii friend,
Today I am going to make a transistor amplifier.2222A Transistor we will use to make amplifier.This amplifier is really working.This amplifier can use to make a mini amplifier.
Let's get started,
Step 1: Take All Components As Given in Pictures
Step 2: Solder 1K Resistor
Solder 1K resistor to the 1st pin and 2nd pin of the transistor as shown in the picture.
Step 3: Solder a Capacitor
Solder the +ve wire of capacitor on the 2nd pin of transistor.
Step 4: Now Solder AUX Cable
Solder the +ve wire of aux cable to the -ve pin of capacitor and then connect -ve wire of aux cable to the 3rd pin of thr transistor.
Now AUX Cable connection is completed.
Step 5: Connect Speaker to the Circuit
Connect -ve wire of speaker to the 3rd pin of the Transistor.
Step 6: Now Connect a Battery
Now we have to connect a 5V battery to this circuit.
Connect +ve wire of battery to the 1st pin of transistor and -ve wire of battery to the remaining speaker wire.
This amplifier circuit we can use to make a mini amplifier.
Step 7: Amplifier Is Ready
Now this amplifier is ready to play songs.you can play songs by aux cable.
you can also play songs by laptop,desktop,mobile phones,mp3 player etc.
Thank you
