12 voltage easy amplifier

12 voltage easy amplifier:

This is a 12-voltage easy amplifier circuit diagram. it’s an easy audio circuit using tda2003 audio ic. this is a mono audio circuit diagram. here in this circuit used TDA2003. we can use the battery. 

pf calculation formula:

How to Read the Value of Ceramic Capacitors? here is the pf calculation formula in an easy way. here we are trying to tell an easy way to find the pf number. the pf is the short form of picofarads. here unit conversion in Microfared, Nanofared, and Picofarad capacitors. Ceramic capacitors have two or three digits code.
