The ideal BJT in the circuit given below is biased in the active region with a $\beta$ of 100 . If $I_B$ is $10 \mu \mathrm{~A}$, then $V_{C E}$ (in Volts, rounded off to two decimal places) is ____________ .

Resistor R₁ in the circuit below has been adjusted so that I₁ = 1 mA. The bipolar transistor Q1 and Q2 are perfectly matched and have very high current gain, so their base currents are negligible. The supply voltage V_cc is 6 V. The thermal voltage kT/q is 26 mV.

The value of R₂ (in $$\Omega $$ ) for which I₂ = 100 $$\mu {\rm A}$$ is ________.

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
