Conductors and Insulators Tutorial – Conductor and Insulator – Electronic  Circuit Theory Btech Projects
CONDUCTORS These are materials in which it is easy to get electrons to move and provide a flow of electric current. Conductors are mostly metals such as gold, silver, copper, iron and lead. Carbon is a conductor as well as some gases (as in fluorescent tubes) and water containing some chemicals. These...

What is an Amplifier ? Amplifiers Tutorial – Amplifier Circuits – Amplifier General Theory – Btech Project
Amplifiers are used to increase the voltage or power amplitude of signals. They have many applications. AUDIO VOLTAGE amplifiers boost the amplitude of signals between the frequency range 20 Hz to 20 KHz. This is the range of human hearing. They are often used as PRE-AMPLIFIERS before the main amplifier. AUDIO...
