QUESTION 15 Calculate the current I E/ZT (in mA) in the series circuit shown. The source voltage E5 Vrms, the resistance is R-47 W , and the inductor reactance is XL = 33 W . (Enter your answer as the number of mA without the units.) 5 V RMS 350 Hz
2.34. A load draws between 20 mA and 40 mA at a voltage of 20 VDC. The available DC power varies between 100 and 140 VDC. (a) Design a voltage regulator using the following components: • Resistors - any size: any number • Zener Diode – regulates for a Zener current of 5 mA to 50 mA. (b) The valție engineering department has found an “equivalent” Zener diode that can be purchased for 70% of the cost of your original...
4.47 In a particular circuit application, ten “20-mA diodes” (a 20-mA diode is a diode that provides a 0.7-V drop when the current through it is 20 mA) connected in parallel operate at a total current of 0.1 A. For the diodes closely matched, what current flows in each? What is the corresponding small-signal resistance of each diode and of the combination? Compare this with the incremental resistance of a single diode conducting 0.1 A. If each of the 20-mA...

In this circuit, C1=10μF, C2=12 μF, and C3=15 μF. The voltage
across the batteries is 20V.
a. Find the voltage across each capacitor and the charge on each
one.
b. These three capacitors are replaced by two equal capacitors
in parallel. What should the capacitance of these two capacitors be
for the two circuits to be equivalent?
