a) Design a circuit with a single opamp to realize V0=V1-4V2, where V1 and V2 are two input voltages.b) Select the resistor values so that no more than .25W is dissipated in any resistor when the input voltages are no larger than 10Vc)If your design uses an LM741 opamp, determine the bandwidth of your circuit
A glass tube with a cross-sectional area of 9^-2 m^2 contains an ionizd gas. The densities are 10^15 positive ions/m^ and 10^11 free electrons/m^3. Under the influence of an applied voltage, the postive ions are moving.
A network connected between terminlas a and b consists of two parallel combinations that are in series. The first parallel combination is composed of a 10 OHM resistor and a 19 OHM resistor.
For the amplifier in Fig. P4.20, the maximum value of VS is 2 V and the op-amp can deliver no more than 100 mA. (a) If +-10 V supplies are used, what is the maximum allowable value of R2 (b) Repeat for +-3 V supplies.
A horizontal beam of negligible weight is 38ft long andis supported by columns on each side. a verticle load of 68000lbs is applied to the beam at a distance X from the left end. find the X in ft so that raction at the left column is 47000 lbs
An AC motor with impedance Z = 4.2 + j3.6 Ω is supplied by a 220 V, 60 Hz source. Determine the reactive power delivered to the load.
give the definition of electrical circuit. draw the simplest electrical circuit and mark the directions of electrical values in it and ohms law. what are the main and the additional elements of the electrical circuit and that are the purpose.
An object of mass m = 0:1 kg is dropped from a high tower. Suppose the magnitude of the force due to air resistance is 0:98v2. (The gravitational constant is g = 9:8 m s2 ). a) Write down the dierential equation satisfied by velocity.
Calculate Vout (f0), Vout (3f0), Vout(5f0), and Vout(7f0) of the frequency spectrum of a triangle wave (A = 10 V and T = 1 ms) passed through a low-pass R-C filter (R = 10 k-ohm and C =5 nF).
In each of the three phases in a balanced delta- connected load is composed of a 10mF capacitor in parellel with a series-connected 470 ohm resistor and 4mH inductor combination, assume a phase voltage of 400 V at 50 Hz
Design a controller with a 4-bit state register that gets synchronously initialized to state 1010 when an input reset is set to 1.
build a cicuit that must be able to operate a 3 amp load of the LED while being able to operate at voltages around 3V or 6V. It must be able to keep the LED on constantly while also being able to pulse the LED.
Find the induced emf as a function of time, for a square wire loop of side length 3m, in the x-y plane with one corner at the origin, due to a changing magnetic flux density B =5xycos(10t)z ˆ Wb/m2
