1. Draw a base-biased circuit. Then, tell me how to calculate the collector-emitter voltage. Why is this circuit likely to fail in mass production if a precise value of current gain is needed?
2. Draw another base-biased circuit. Draw a load line for the circuit and tell me how to calculate the saturation and cutoff points. Discuss the effects of a changing current gain on the location of the Q point.
Two stages are cascaded to result in an overall gain of 680 V/V.The loaded gain of the first stage is 36 dB. What must the gain ofthe second stage be in dB to satisfy this specification In V/V
Most motorcycles have engine speed tachometers, as well as speedometers, as part of their instrumentation. What differences, if any, are there between the two in terms of transducers?
For the network of given figure and the applied source: - Determine the source voltage vs. - Find the currents i1 and i2.
The 3phSM is used in a pumped storage application which has a head of 250 m. When pumping or generating, it operates at 84% efficiency, rated stator conditions. Determine the turbine flow when (1) generating and (2) pumping.
illustrates how the forces can vary in problems of this type. A hiker, who weighs 739 N, is strolling through the woods and crosses a small horizontal bridge. The bridge is uniform, weighs 3250 N, and rests on two concrete supports
Three identical coils, each having a resistance of 10 ohms and a reactance of 10 ohms are connected in (i) star (ii) delta, across 400v, 3-phase supply.- Find in each case the line current and the readings on each of the wattmeters connected to mea..
Write a program to implement this process.
The forward transmittances of unity feedback tracking systemsare given below. For each, find the type number of the system, thesteady state error coefficients k0,k1, and k2 and the steady stateerrors to unit step ramp, and parabolic inputs.
A system is described by the differential equation ty'(t)-8y(t)=x(t). Classify the system as to linearity, time-invariance and stability. Show that a system with exicitation x(t) and response y(t) described by y(t)=u(x(t)) is nonlinear, time invari..
A 240V, short shunt, cumulative compound generator is rated at 100A. The shunt field current is 3A. It has an armature resistance of 50 milli-ohm, a series field resistance of 10 milli-ohm a field diverter resistance of 50 milli-ohm and a rotation..
Ask the students what the impact of this would be on international athletic competitions and individuals who are thus genetically enhanced. Provide your argument with literature citation.
How does ambient temperature affect the forward bias voltage of a diode. For some significant enough increase in temperature, how will the voltage across the diode terminals be affected
