In Fig. 5-45, the LED does not light. Which of the following are possible troubles?
a. V130LA2 is open.
b. Ground between two left bridge diodes is open.
c. Filter capacitor is open.
d. Filter capacitor is shorted.
e. 1N5314 is open.
f. 1N5314 is shorted.
a). Without calculating E(z), find its poles. b). Give the rule that you used in part (a). c). Verify the results of part (a) by calculating E(z). d). Compare the zero of E(z) with that of E(s).
Design a dc power supply that provides a nominal dc voltage of 12V that will supply a load current of up to 30mA. Use a Bridge rectifier in your design and isolate your circuit by use of a transformer at the input.
Make a transfer function with numerator p(s) and denominator q(s)that will separate only the 3cos(4t) portion from the noise corrupted function: u(t) = sin(25t) + 3cos(4t) + n(t) wheren(t) is random noise. The degree of the polynomial on the denom..
For the emitter bias network of Fig, determine:- IB, IC, VCE.- Given that ICQ = 2 mA and VCEQ = 10 V, determine R1 and RC for the network.
if 4 cells each rated for 2v, 0.15A connected as batterries in three different ways. find voltage and current rating of each type. (Hint - all in parallel, all in series, two groups of series connected in parallel)
Mechanical sensing elements as two-port networks: - Overall two-port representation - Equivalent circuit with Thévenin output- show the representation.
A 220 V dc shunt motor runs at 1400 rpm on no-load drawing an armature current of 2.4 A from the supply. Calculate the motor speed for an armature current of 60 A. Assume that the flux/pole reduces by 4% armature reaction. It is given that Ra = 0...
Finding appropriate source for the electrical load, Have four circuits. One takes 9Vdc, two 5Vdc, and last one takes 12Vdc. Have variable transformer for source. How do I calculate or choose the voltage needed to run all four circuits with out blo..
Load 1: Wye-connected load that consumes atotal 3-phase power of 3.6 kW at 0.8 power factor lag, when the generator voltage is set so that the voltage at the load is 480volts line-to-line. Load 2: Delta connected load that consumes 2kW+ j1 KVAR of..
A practical discussion of the function of each of the three terms (proportional, integral, derivative) and An explanation of the affects that changing each of the three tuning constants has on the resulting control response.
What highly volatile, water-insoluble chemical competes with naphthalene as a raw material needed to manufacture the intermediate phthalic anhydride used in the production of certain resins and polyesters?
Design the combinational logic circuit for an elevator controller such that the option to go up or down by only one floor is disabled. Assume that the building the elevator is in has 4 floors. Your inputs are the current floor and the next request..
