the input voltage is 20V with phase angle -90 degrees and a 5 ohm resistor in series with each other. There is a 3 ohm resistor and j4 ohm inductor in series with each other. There is a 4 ohm resistor, a -j13 ohm capacitor, and a 10 ohm resistor in series with each other.These two series circuits are in parallell with each other.The output voltage is measured across the 10 ohm resistor. Find the output voltage and total impedance.
A series circuit has a resistance of 1 ohm and an inductance of 1 ohm. The voltage across the circuit has an amplitude of 15 volts and a phase shift of 30 degrees. What is the current of the circuit in frequency and time domain
A special case of the NON-inverting amplifier has Rf = 0.0 ohms. That is, the op amp output is connected directly ("short circuit") to the inverting input and Ri is removed entirely (i.e., Ri = infinite ohms; "open circuit").
Describe the charge diffusion and drift in a PN junction, without and then with an applied voltage
Explain why the short-circuit method for determining the Thevenin resistance of a circuit cannot be applied if the circuit does not contain any independent current or voltage sources.
Find the associated answers for: total circuit impeadance (Zt), Current source (RMS), Vc (RMS) w/ power factor, Vr (RMS), all in complex form/ rectangular form. Remember each question has to be done three times, one for each frequency.
