If we want to build an amplifier, then we should bias the BJT to operate in ..... mode.

Assume we want to build a shunt regulator using a 5.1 V zener diode. The input voltage is 10.8 V, the knee current IZK = 0.2 mA, and the max load current is 4.4 mA. The series resistance (the current limiting resistance connecting the input source and the zener diode) should be selected to be smaller than ..... Ohm.

For a BJT in active mode, VBE is approximately equal to ..... V.

Assume VON = 0.8 V.

The transistor is best modeled as a .....

For a BJT biased in active mode, the largest current flows in the ..... terminal.

For a BJT in active region, if IC = 11.6 mA and Beta = 77, then IE is equal to ..... mA.

Hint: Do not neglect base current.

For a BJT in active mode, VCE needs to be larger than ..... V.

Assume VCE,sat = 0.16 V.

Assume we want to build a shunt regulator using a 5.1 V zener diode. The input voltage is 10.7 V, the knee current IZK = 0.2 mA, and the max load current is 8.9 mA. The series resistance (the current limiting resistance connecting the input source and the zener diode) should be selected to be smaller than ..... Ohm.

The LED needs to be operated using DC current, that's why typical commercial LED bulbs contain a power supply circuit that converts the AC from mains to DC.

For a BJT in active mode, if IC = 30.7 mA and Beta = 116 then IB is equal to ..... uA.
