please check the way i explain the roles of components in this amplifier circuit

This is a test post for Nyame Ephraim Mechane, but please respondPlease kindly take a quick look at the way I explain the roles of components in this amplifier circuit 

Ephraim... I posted this to check if there are any difficulties in posting your diagrams.It is possible to post .DOC files but you have to download them rather than opening them directly, which is a minor inconvenience.  Just use the "Attach files" button in the question posting screen.  You could also post an image file (JPG/PNG/BMP) and/or a PDF this way.I would reword as follows:"The   voltage divider centre  point holds  the   base  at a   DC potential  around 0.6V above the desired emitter voltage for the BC108 transistor (You should give this voltage)"
"The   collector   resistor   sets   a   limit   of   the   collector  current   and   also   the loading impedance for the transistor to develop a voltage swing across. It also   sets  the   load   line  output   swing   to   the   minimum  and   maximum values;   it   sets   the   maximum   power   dissipated   in   the   collector   of   the transistor."That's a little cumbersome, but basically right. 
"the 20kΩ resistor is use to take out DC from the capacitor,"
It is a load for the circuit for test purposes (it may not be needed when a real load (maybe another amplifier stage) is connected.  It does not "take out" DC from the cap, but provides a discharge path for the capacitor so it does not get a permanent charge. the voltage divider centre pointholds the base at a DC potential just above the required base emitterjunction bias voltage of 0.6 or 0.7 for the BC108 transistor the voltage divider centre pointholds the base at a DC potential just above the required base emitterjunction bias voltage of 0.6 or 0.7 for the BC108 transistor

I would prefer to see image (JPG/PNG) or PDF file rather than .doc.The 20Kohm resistor is needed to provide a DC path to ground for connection/node between the 1000nF capacitor and the voltmeter/oscilloscope. Circuit simulators generally require that all nodes have DC paths to ground, though the resistances of the paths to ground can be very large.
