# impedance

1. ### Impedance

If you have a common circuit with 1 resistor, 1 capacitor, and 1 inductor. Inousoidal voltage and current is applied with angular frequency, ω. Then you want to use the jω-method and express the total complex Impedance, Z, of the above circuit in terms of R,L,C and ω. Answer in the form Z = a +...
2. ### Voltage Magnitude, Phases, Current for Bus (Load Flow)

Say there are 3 buses of: Bus 1: Slack bus with a voltage source of E=1.0 and phase of 0° Bus 2: a generator and a load. Bus 3: a load. The line impedance are given below: z12 = 0.05 + j0.1 z13 = 0.02 + j0.05 z23 = j0.05 z11 = -j100 z22 = infinity z33 = -j40 The generators and loads are given...
3. ### Given 3 buses with line impedance, generators and loads provided, where must the protection circuit be allocated?

The 3 buses are Bus 1: Slack bus with a voltage source of E=1.0 and phase of 0° Bus 2: a generator and a load. Bus 3: a load. The line impedance are given below: z12 = 0.05 + j0.1 z13 = 0.02 + j0.05 z23 = j0.05 z11 = -j100 z22 = infinity z33 = -j40 The generators and loads are given below...
4. ### How to change trace width and spacing of diff pairs in the design using MentorGraphics Hyperlynx SI

Hi, I am simulating my postgraduate project using Hyperlynx SI tool. I am testing on PCIe traces of my design. I did my design using Altium and I exported to Hyperlynx file to do the simulation. But I cannot change the trace width and spacing of Differential pairs using Hyperlynx SI tool. Is...
5. ### Calculation of power factor in a RLC-circuit

Hello, I got a homework exercise about the calculation of the power factor in a RL-circuit and in a RLC-circuit. The question consists of 3 sub questions, I have managed to calculate the first 2 however I am struggling with the third one. For the calculation of the third question, the other 2...
