How do i calculate the IB and resistance values of r1,r2,r3,r4 required to do the following to the collector current when each pushbutton is pressed in turn:
1.When pb1 is pressed transistor is fully saturated and near 1 amp flows on Ic ?
2.When pb4 is pressed transistor operates in active region and makes Ic = 500ma ?
3.When pb3 is pressed transistor operates in active region and makes Ic = 10ma ?
4.When pb2 is pressed transistor operates in active region and makes Ic = 0.1ua ?
The transistor is a Bc548A npn bjt the circuit is purely just to learn about a transistor active region and how to calculate required biasing current.
