An amplifier with Ri = 2 kΩ, Ro = 500Ω, and Rmoc = -107 is operated with a 1-kΩ, load. A source having a Thévenin resistance of 1kΩ and an open-circuit voltage of 2 cos(200 πt) mV is connected to the input terminals. Determine the output voltage as a function of time and the power gain.
for a Si conductor of length 5um, doped n-type at 10^15 cm^-3,calculate the current density for an applied voltage of 2.5 Vacross its legth. how about for a voltage of 2500V the electronand hole mobilities are 1500 cm^2/V-s and 500 cm^2/V-s,respec..
Show that for wires of identical dimensions but made of different materials, such as copper and aluminum, the resistance is proportional to the resistivity of the material. the resistance of a certain copper wire is 1.5.
A high-pass filter with C=30pF. R= 40 kohm A) What is the cutoff frequency The output of this filter is connected to an amplifier with an input resistance of 60 kohm. B) Sketch and label the new circuit. C) What is the new cutoff frequency
According to the TL081 datasheet, the input noise voltage and current of TL08 are 25 nV/ÖHz and 0.01 pA/ÖHz, respectively. Assuming the circuit operates under room temperature, please find the output voltage Vout

You will be asked to design the logic circuit such that a 7-segment display can be know the number of people who are in the room. Note: never going to be the case that a person joins the room at the same time another person leaves.
A full wave rectifier has 50 Hz input signal, a peak voltage output VM of 12 V, and an output load resistance of R=10 kOhm. If ripple voltage is to be limited to Vr=0.2 V , determine the required capacitance value.
A 480 V permanent magnet ac motor is consuming 10 kW at power factor 0.80 lagging. Its speed is 1800 rpm. The winding resistance is 0.5 ohms per phase. Core losses are 100 W.
There are three gates. Each gate can be opened or closed depending on the three logic inputs: (a, b, c). Gate open logic=1, gate close= logic 0. Design a logic circuit so that no adjacent gates or outputs (x, y, z) are open at the same time.
For the given circuit, determine the function of it I.e. is it OR gate? Or AND gate,.. Show all your answer, also draw the symbol and truth table of it.
