About this Exam

Prepare with the Cameroon Baccalauréat Série F2 Practice Questions - Cameroon Baccalauréat Technique Série F2 (Électronique) Exam practice quiz. This question bank includes 100 questions covering text, voltage, omega, input, and amplifier. Use it to review important concepts, identify knowledge gaps, and build confidence for the related exam, course, or assessment.

Sample Questions

Question 1
In an ideal operational amplifier (AOP idéal) operating in linear mode with negative feedback, what are the theoretical values for the differential input voltage ($\varepsilon = V^+ - V^-$) and input bias currents ($I^+, I^-$)?
ε = 0 V (virtual short-circuit / court-circuit virtuel) and I^+ = I^- = 0 A (infinite input impedance)
ε = +15 V and I^+ = I^- = 10 mA
ε = 0 V and I^+ = I^- = infinite
ε = V_sat and I^+ = I^- = 1 mA
Question 2
In an inverting op-amp amplifier circuit with input resistor $R_1 = 10\text{ k}\Omega$ and feedback resistor $R_2 = 100\text{ k}\Omega$, what is the closed-loop voltage gain $A_v = \frac{V_{out}}{V_{in}}$?
-10
+10
-11
+11
Question 3
A non-inverting op-amp amplifier has $R_1 = 4.7\text{ k}\Omega$ connected from the inverting input to ground and a feedback resistor $R_f = 47\text{ k}\Omega$. If the input signal is $V_{in} = 0.2\text{ V}$, what is the output voltage $V_{out}$?
2.2 V
2.0 V
-2.0 V
-2.2 V
Question 4
What is the primary function of a voltage follower (suiveur de tension / buffer amplifier) with $A_v = 1$ in an electronic circuit?
Impedance matching: provides very high input impedance and very low output impedance to prevent signal attenuation from loading effects
Voltage amplification to boost millivolt signals to 100 volts
Phase shifting by exactly 90 degrees to generate quadrature signals
Rectifying AC signals into pulsating DC current
Question 5
In an op-amp integrator circuit (montage intégrateur) with input resistor $R$ and feedback capacitor $C$, what is the output voltage $v_{out}(t)$ for an input voltage $v_{in}(t)$?
v_{out}(t) = -\frac{1}{R C} \int v_{in}(t) \, dt + V_0
v_{out}(t) = -R C \frac{dv_{in}(t)}{dt}
v_{out}(t) = -\frac{R}{C} v_{in}(t)
v_{out}(t) = +\frac{1}{R C} \int v_{in}(t) \, dt
