A circuit element is hidden inside a potato sack and draws a current which varies with time t, measured in seconds, i(t) = 0.04 e(-4400 · t) Amps, while the voltage drop across this element is given by the function v(t) = 6.061 (1 - e(-4400 · t)) Volts.
Identify this circuit element as a capacitor or an inductor. What value will it have considering a passive sign convention? If the circuit element could be either a capacitor or an inductor, state both possible values. If the circuit element must be a capacitor or must be an inductor, state both possible values.
Show how to make a two-digit digital-to-analog converter by appropriately scaling the input resistors of a summing amplifier. The digital input represents two digits, each consisting of four lines that represent the values 1, 2, 4, and 8 for the r..
A separately excited 300V DC motor has an armature resistance of 1ohm and a field resistance of 100 ohm. The field Voltage is 200V. The no load speed is 1200 rpm and no load armature current 2A
describe the steps in the procedure based on grid-based color/texture histogram similarity measure for database retrieval of images that closely match a query image.
A 0.51-kg block is hung from and stretches a spring that is attached to the ceiling. A second block is attached to the first one, and the amount that the spring stretches from its unstretched length triples.
Write a program in C not C++ that reads 20 integers from the user and sums the odd and even numbers together. Also have the program output the ratio of the odd numbers to the even numbers.
an electrical transformer dissipates heat equivalent of 3000 kW/h. the inlet and outlet temperatures of the cooling water are 55C and 15C respectively. calculate the mass of the cooling water in a minute.
A bandpass filter with a center frequency of 6kHz, a 3dB banwidth of 1 kHz, and a 50 dB bandwidth of 2kHz is connected to a signal generator that outputs a one volt square wave at a frequency of 2kHz. A spectrum analyzer is connected to the filter..
In an electroplating process, copper (ionic charge +2e, atomic weight 63.6 g/mol) is deposited using a current of 10.0 A. What mass of copper is deposited in 10.0 minutes. Avogadro's number is 6.022 × 1023 molecules/mol and e = 1.60 × 10-19 C.
Explain why it is unlikely one would encounter a circuit exhibiting a critically damped response in practice. What impact would time and temperature have on a supposedly "critically damped" circuit
Design and Analysis: The simple high-pass and low-pass filters shown to the right have been analyzed in class. The transfer functions are H-HP(f) = j fRC / ( 1 + j fRC ) and H-LP(f) = 1 / ( 1 + j fRC ). In either case the -3dB frequencies are F-3D..
The transformer is supplying a load of 325 MVA, with 0.93 power factor lagging at a voltage of 24 kV (line-to-line) on its low-voltage side. It is supplied from a feeder whose impedance is 0.11 + j2.2 ohms connected
Design a 2-bit counter that, when f = 1, counts in the repeating sequence: 0, 2, 3, and when f = 0, counts in the reverse direction. Use T flip-flops. (a) Construct a state diagram or state table.
