1. The forward and reverse DMM diode test reading is 0.7 V and 1.8 V. Is this diode good?
2. Which diode would you select in the 1N4000 series if it has to withstand a peak repetitive reverse voltage of 300 V?
3. The data sheet shows a band on one end of the diode. What is the name of this band? Does the diode arrow of the schematic symbol point toward or away from this band?
A delta-connected source has a line-to-line voltage rating of 470 Vrms. Its wye-connected load has a power rating of 2125 W with a pf of .85 lagging. Find the rated phase currents.
Switch the cursor on. You will see two vertical lines on the screen. At the same time a further display window opens in which the chronological position of the two lines is given in figures. Now move the cursor lines, measure instantaneous values,..
Design an amplifier circuit which uses an OpAmp and is powered by dual 15 V power supplies, and which has the following characteristic at low frequencies: Vout = 3V1 - 5V2 1. State the information which is extracted from the equation.
Derive the exact characteristic impedance for a two-section binomial matching transformer for a normalized load impedance
As speed increases, the lower lamp, L1 lights, then L1 and L2, then, L1, L2, and L3, until all lamps light at the highest speed. Once all the lamps illuminate, no further increase in speed will have any effect on the display.
Neglect base currents. The maximum emitter current for all transistors is 0.8 mA. Assume the input logic voltages I are compatible with the output logic voltage. Determine all resistor values.
an inductor motor is connected to a 220 v 60hz supply and drews 5.0a at 0.85 lag power factor. 1. what value of
Design an up / down counter with four states (0, 1, 2, 3) using clocked J-K flip-flops. A control signal x is used as follows: When x = 0 the machine counts forward (up), when x = 1, backward (down).
An electron is confined inside a potential well with infinite walls. The width of the of the wells = 5nm. What is the probability of finding a electron within 1nm from either wall if the electron is at: A)the lowest energy level B). the 2nd lowest ..
Find the transformation ratio of a transformer having 350 turns on the secondary winding and 7000 turns on the primary. What voltage must be applied to the primary of the transformer to develop an open-circuit secondary voltage
Determine the transfer function for a second order band pass filter with specifications. Chebyschev type with 1 db ripple in the pass band Lower cutoff frequency = 100 radians/sec Upper cutoff frequency = 169 radians/sec Pass band gain = 1
A phase modulation (PM) signal s(t) has a modulating wave m(t) = Amcos(2ðfmt) and phase sensitivity kp = 10 radians/V. What would be the modulating signal if the same signal s(t) is generated by frequency modulation (FM) with frequency sensitivity..
