Consider the circuit shown in the figure. Assuming V_BE1 = V_EB2 = 0.7 volt, value of the dc voltage V_c2 (in volt) is _______

If the emitter resistance in a common-emitter voltage amplifier is not bypassed, it will

A cascade connection of two voltage amplifiers A1 and A2 is shown in the figure. The open-loop gain A_v0, input resistance R_in, and output resistance R₀ for A1 and A2 are as follows:
A1: A_v0 = 10,R_in = 10 kΩ ,R₀ =1 kΩ
A2 : A_v0 = 5,R_in = 5 kΩ , R₀ = 200 Ω
The approximate overall voltage gain $$\frac{{\mathrm V}_\mathrm{out}}{{\mathrm V}_\mathrm{in}}$$ is ______.

In the circuit shown, the PNP transistor has $$\left|{\mathrm V}_\mathrm{BE}\right|=0.7\;\mathrm V$$ and β = 50. Assume that R_B = 100 kΩ. For V₀ to be 5 V, the value of R_C ( in kΩ) is _____________.
