what two terminals of NPN are connected to the positive power supply terminal

C. Base and Collecter

what component does the base terminal need?

A. Resistor

What terminal is grounded in NPN

C. Emitter

NPN Base current is

B. Flowing towards the base terminal

PNP base current is

A. Flowing away from the base terminal

Cutoff of transistor

A state in which a transistor is fully turned off, resulting in no current flow between the collector and emitter terminals.

-VB<VE

-VBE<0.7

-VCE=VCC

-Ic= 0

Active of transistor

A state in which a transistor is fully turned on, allowing current to flow freely between the collector and emitter terminals.

-VBE>or equal 0.7V

-0<VCE<VCC

-0<Ic<Isat.

-Ic=Beta(Ib)

-Ib increases, Ic increases

Saturation of transistor

A state in which a transistor is fully turned on, allowing maximum current to flow between the collector and emitter terminals.
-VBE<0.7V
-VCE is close to 0V
-Ic is at maximum value.

what’s beta?

Gain or amplification factor of a transistor. It is the factor by which current is amplified in the circuit/

Sinking

refers to the process where the NPN transistor allows the current to flow from the collector to ground

Sourcing

refers to the process where the PNP transistor allows current to flow from the emitter to the load, supplying power to the circuit.
