1. your resistive load value
2. load current ( which is depend on the output voltage divided by the load resistive )
3. your total gain after connecting the resistor ( this will help to find the Ro of the amplifier and the gain before connecting it )
ok lets take for example voltage gain of 100Milivolt
i am trying to learn electronics self, i am reading the books electronics principles by alberto malvino, can you make one amplifier now in similary way PLEASE
THNX
