How To Use Transistor As An Amplifier Circuit Full Tutorial
What Is An Amplifier ?
An amplifier is a circuit, that has multiple power gain greater. Audio Amplifier Amplify Signals In The audio sound range.
In this video, we’ll tech you making a simple amplifier circuit using transistor. For power source, we’ll use only DC-12v.
To make this amplifier circuit, we might need some electronics component. Those component list have to been given below.
Component List :
1. Transistor – A1941
