Option b)
It coincides with 1/bandwidth and it's the time value in the first order lag 11+jωτ11+jωτ or 11+τs11+τs . In radioactive decay they use 50% ('half-life)
B)

INSTRUCTIONS: Read the questions carefully and answer the following items accordingly. Show your solution properly. Q6 An Amplitude-versus-time characteristic curve is given in Figure 2. It is the graphic response of a DC supplied series RC circuit. Determine: a) Draw the circuit, name the parts of a Series RC DC circuit and show the mathematical relations of initial current, voltage across the capacitor at charging state and stored energy by the capacitor. (2 Mark) b) Describe in detail about the...
You can use any software of your choice
Begin by connecting the waveform generator to the series combination of a 0.2uF capacitor (use a decade capacitor box) and a 1 ks resistor (use a decade resistor box). Generate a 500 Hz, 8 Vp- p square wave with a 4 Volt offset and observe this waveform on the oscilloscope's Channel 1. Monitor the voltage drop across the capacitor on Channel 2. Figure 1 shows the schematic for the RC circuit 1k...
Laplace Analysis of the Permanent Magnet Brushed DC Motor
and the right final answer should be like this
A permanent magnet brushed DC motor (the type of motor that spins when connected to a constant voltage) can be described by the simplified model tö+) = Kv, where o is the angle of the motor shaft, v is the voltage applied to the motor, 7 is a positive constant known as the motor time constant, and K is a positive constant...
For multiple-choice questions, cirele the letter of the one best answer (unless more than one answer is asked for). Show your work on free-response questions. Be sure to use proper units and significant figures in your final answers. Organization and neatness count, too. Do NOT use red ink please reserve that color for grading. 1. For each arrangement of point charges below, neatly draw between 12 and 16 electric field lines. Indicate direction on ALL field lines with arrowheads. Show...

Please note that D4 is the one that was destroyed not D1.
Please I posted this but they answer it differently
QUESTION (2) Due to an abnormal operating condition, Diode D4 in this full-wave rectifier circuit was suddenly destroyed, and stopped Vconducting in both forward and reverse directions (i.e. open circuit) C- R Assume that all other diodes are ideal with zero forward voltage drop and that the time constant RC- 5 ms. stt) 10V For a 1 kHz triangular...
Objectives: To learn transient behavior of series RC circuits To observe of time constant and its effect on charging process of capacitor using pulse waveforms Equipment: Oscilloscope Function generator Resistors (1 k) Capacitors (1 uF) Breadboard Pre-Lab Questions A pulse is a voltage or current that changes from one level to the other and back again. If a waveform's high time equals its low time, it is called a square wave. The length of each cycle (one positive peak and...
need answer. dont know. please select the correct one
Rc-4.3 k2 RB 500 kS2 RL 100 k2 Cc 10 uF Vs Assume transistor is NOT ideal and hence do not ignore the transistor high frequency capacitances GT and Gu Regarding the amplifier circuit above, which of the following statements is INCORRECT? There is only one incorrect sentence (you might need to draw freq response and draw equivalents before answering) When calculating the upper 3 dB frequency, the time constant is...
1) Design a low-pass RC device with the following specifications: a) Input x(t) and output y(t) b) Bandwidth which is defined as the range of frequencies (from 0 Hz to ??, the − 3dB point ) allowed to pass through without significant attenuation = 100Hz c) Static gain = 14dB d) The system has −20 dB/decade rolloff at high frequencies (thus first-order LP filter) Assume that you have one and only one resistor value available to you, and that resistance is...
