Fоr the circuit shоwn belоw, аssume collector current I C Q = 4 mA I_{CQ} = 4 , text{mA} , β = 100 betа = 100 (with I E ≈ I C I_E аpprox I_C ), and V B E ( on ) = 0.7 V V_{BE(text{on})} = 0.7 , text{V} . The emitter resistor R E R_E is given as 1 k Ω 1 , text{k}Omega , as indicated. Determine the value of R 1 R_1 that ensures the circuit remains bias-stable. For this calculation, you do not need the values of R C R_C or V C E V_{CE} . Assume the transistor operates in the forward active region. Select the value closest to your result. find R1.jpg
