Q1: For the symmetric directional coupler shown below, if the directivity is infinite and the forward attenuation is C=20 dB, find the transmitted power from the source (Pt)and ( p x). 171 1 mW B2 Pt P 9 mW B1 200 mW C=20 dB Px ΖΙ

Conductor spacings, types, and sizes do have an impact on the series impedance and shunt admittance? True or false? And why?

Hi, Help me with this circuit question

Given a delta wye circuit with L=265mH, C=27uF, f=60Hz, and R=100Ω, complete the table and find the impedance in rectagular and polar form. Show solutions and do not round off answer until the final answer. Round off final answer to five decimal places if applicable.

How do I find the effective impedance as seen by the source at the primary side of the ideal transformer?

i need the answer quickly

a step down chopper fed from 220V dc, is connected to RL load with R=10 ohms and LL=150 mH chopper frequency 1250HZ and duty cycle is 0.5 calculate the maximum value of load current (a)20.587A(b)8.521A (c)25.415A (d)12.478A

QUESTION 12 The ripple voltage of a full-wave bridge with a capacitive filter is O a. less than the VRIP of a half-wave rectified power supply with the same capacitive filter O b. at the same frequency as the input frequency O c. not dependent on the value of the load resistor O d. equal to the VP of the transformers secondary voltage

The VSWR on an 50-Ohm transmission line is 5. The distance between successive voltageminima is 80 cm while the distance from the load to the first minimum is 30 cm. What are thereflection coefficient and load impedance

please explain each part on paper thank you i will like
