 How To Make A Single BC547 Transistor Audio Amplifiers Circuit Diagram Using BC547

Today I am going to make an amplifier using Double transistor of BC547.

Take All Parts As Shown Below

Components required 

(1.) Transistor - BC547 x2

(2.) Resistor - 10K x1

(3.) Aux cable x1

(4.) Power supply - 5V DC

(5.) Capacitor - 63V 1uf/2.2uf x1

(6.) Speaker x1

Firstly we have to connect both transistors.

Next we have to connect 10K resistor to the circuit.

Next solder +ve pin of 2.2uf capacitor to base pin of the transistor-1 as you can see in the picture.

Connect speaker wire to the circuit.

Solder +ve wire of speaker to collector pin of transistor-1 and

solder -ve wire of speaker to collector pin of transistor-2 as you can see in the picture.

Next solder +ve (Left/Right) wire of aux cable to -ve pin of capacitor and

Next connect 5V DC Power supply wire to the circuit.

NOTE: We can give input power supply with 5V charger,5V battery,.....5VDC.

Connect +ve clip of power supply to collector pin of transistor-1 and

-ve clip to emmiter pin of transistor-2 as you can see in the picture.

Now Plug-in aux cable to mobile phone/laptop/tab.....and play songs.
