A) A pure DC current of 20 A flows through a given resistorproducing certain amount of heat. What peak value of AC current isrequired to produce the same amount of heat?B) What rms, or effected value, of AC current is requiredto produce the same amount heat?
The disk uniformly rotates in air about its axis (perpendicular to the disk) with an angular velocity . Find the magnetic flux density vector at an arbitrary point along the axis of rotation. Assume that the charge distribution over the disk remai..
A square-law modulator for generating an AM wave relies on the useof a nonlinear device. The given figure depicts the simplest form of such amodulator. Ignoring the higher order terms, the input-output characteristics of thediode-load resistor
A silicon p-n-p transistor has impurity concentrations of 5*10^18, 2*10^17, and 10^16 cm^-3 in the emitter, base, and collector, respectively. The base width is 1.0 um and the device cross-section area is 0.2 mm^2.
A 50 ohms lossless transmission line is to be connected to a load of 25 ohm. Use a lamda/4(quarterLamda) length of line of unknown impedance between the load and the 50-ohm line to match it,
Suppose we want to construct an amplifier with a closed-loop gain of 50. We want the gain to vary by no more than +/- 5% while the open-loop gain varies by +/- 50%. Determine the values for a and b that will satisfy these constraints.
Explain the difference between TDM and TDMA.
Store the arrival times in memory locations starting from $1000.(Do this is in C. Store the results in an array and don't worry about the speci c location of the results.)
We have v1(t)=10cos(wt+30degrees). The current i1(t) has an rms value of 5A and leads v1(t) by 20s. (The current and the voltage have the same frequency) Draw a phasor diagram showing the phasors.
Which sample produces greater Hall voltage: long and narrow or short and wide Thickness (d) is same in both the cases. With little explanations please. 1) If the concentration of scattering centers increase in the semiconductor, would it increase o..
Is there any easy way to understand nodal analysis with voltage source and direction of current Where to start studying from if there is problem with understanding concepts
