Transistor amp

Learn how to assemble a transistor amplifier circuit step-by-step on a breadboard. In this hands-on electronics tutorial, we walk through component placement, capacitor polarity, resistor positioning, transistor orientation, and final oscilloscope testing.

This video is perfect for students, electronics beginners, and anyone learning how transistor amplifiers work in real circuits.
🔧 What You’ll Learn
How to read a schematic for component values
Correct polarity for electrolytic capacitors
Positioning C1, C2, C3, R1, R2, RC, RE1, and RE2
Proper placement of transistor Q1 (base, collector, emitter)
How to straddle capacitors across power rails
How to connect jumpers to complete the signal path
Hooking up a function generator to the circuit
Connecting an oscilloscope (CH1 and CH2) correctly
Final test output of the amplifier
⚡ Circuit Setup Recap
C1 across terminal strip socket 33
R1 from socket 33 to 24
R2 from socket 33 to 40
Q1 placed with base tied to negative side of C1
C2 placed on the collector of Q1
RC placed vertically on collector
RE1 and RE2 placed on the emitter
C3 placed in parallel with RE2
Load resistor R2 connected across negative of C2 and C3
Function generator: 100 mV peak, 1 kHz
Power supply: 10V DC
