Can You show me how to solve the following: If a 5k resitor is connected between the cathode of a 6.2V ZENER diode and a 12V power supply.The anode of the diode is connected to 6V.How much current will flow through the diode?
Can you help with the following problem? If an electrical load operates at 240 Vrms.The load absorbs an average power of 8kW with .8 lagging power factor.How do I compute the complex power of the load and impedance?
An Operational amplifier has a gain of 20. The input is 125 mV and the input bias current is zero. The output voltage is 2.510V. What is the offset voltage? How do I solve this problem?
Can you help solve the following problem? An RC series circuit has a voltage source of 10Vac, a resistor of 10 Ohms, and a capacitor with an impedance of -j10 OHMS. What is the magnitude and phase angle of the current flow through the capacitor?
A saturated npn transistor has a base to emitter-applied voltage of 0.6V. The collector to emitter voltage is 0.2V. The collector current is 12mA. The beta value of the transistor is 30. What is the emitter current?
A 4:1 step down transformer uses a 60Vac source on the primary windings. There is 120mA flowing through the load resisitance on the secondary windings. What is the resisitive load? Is it 125 ohms? 15V/.120=125
What is the output horsepower? Efficiency?
If a fully loaded 440V, three-phase motor draws 12.4 A at 86% power factor (pf). It's speed is 1730 rpm and its torque output to a mechanical load is 29.1 lb-ft x 1.356 = 39.5 Nm. What is the output horsepower? Efficiency?
How would I sketch a bode plot for the following transfer function: V2/V1=20jf/10,000/(1+jf/10,000)(1+jf/1,000,000)
RL Circuits: Growth and decay of current in inductor
See attached circuit. Note current source is 2A,Resistors are 2 Ohms, Inductor 2H. Assume that the switch has been open for a long time and that it closes at t=0 sec. The switch remains closed thereafter. How do I solve for Vx(t) and Ix(t)?
See attached dwg. Can you please show me how to find the magnitude of Z (The impedience "looking in") as a function of frequency from 10Hz to 100KHZ? Note the inductor is 1mH the resistor 100 Ohms and the cap 1uF.
