The formula for IC is IC IE IB TF The ratio IEIC is betadc

The formula for I_C is I_C = I_E - I_B. (T/F)? The ratio I_E/I_C is beta_dc. (T/F)? Two important yet easily measured quantities that can help determine if a transistor amplifier is operating correctly are What is beta_dc factor of a BJT? When a transistor is operated in the active region, changes in the collector supply voltage V_CC

Solution

Question 17. It is true..ie = ic + ib then Ic=Ie- Ib

Question 18. It is false. Because ic/ib = beta DC....

Question 20. Beta DC is a amplification factor..it is used to solve the equations when collector current, emitter current or base current known. Ic= beta *Ib and Ie=(beta+1)Ib

Question 21. When transistor is in active region it acts as a regulator.

V0=Vcc-Vc, Vc=Ic*Rc, Ic=beta*Ib, 0v<V0<Vcc
