AI Thread Summary
To receive help with past examination questions, it's essential to post in the appropriate Homework Forums and demonstrate your current understanding of the topic. Specifically, for question Q1b, the discussion emphasizes the importance of showing your work to receive hints and guidance. Participants are encouraged to explain their knowledge of Thevinin and Norton equivalent circuits, including their differences and conversion methods. This approach fosters a more effective learning environment. Engaging with the community in this manner can enhance understanding and problem-solving skills.

Welcome to PF. Homework questions should be posted in the Homework Forums, and when you post a homework question, you need to show your work so far. We can give you hints and suggestions when you get stuck, but we need to see your work. We do not answer homework (or exam) questions for you.

Like, tell us what you know so far about Thevinin and Norton equivalent circuits. How are they different? How do you convert one into the other?
 
Very basic question. Consider a 3-terminal device with terminals say A,B,C. Kirchhoff Current Law (KCL) and Kirchhoff Voltage Law (KVL) establish two relationships between the 3 currents entering the terminals and the 3 terminal's voltage pairs respectively. So we have 2 equations in 6 unknowns. To proceed further we need two more (independent) equations in order to solve the circuit the 3-terminal device is connected to (basically one treats such a device as an unbalanced two-port...
suppose you have two capacitors with a 0.1 Farad value and 12 VDC rating. label these as A and B. label the terminals of each as 1 and 2. you also have a voltmeter with a 40 volt linear range for DC. you also have a 9 volt DC power supply fed by mains. you charge each capacitor to 9 volts with terminal 1 being - (negative) and terminal 2 being + (positive). you connect the voltmeter to terminal A2 and to terminal B1. does it read any voltage? can - of one capacitor discharge + of the...
Thread 'Weird near-field phenomenon I get in my EM simulation'
I recently made a basic simulation of wire antennas and I am not sure if the near field in my simulation is modeled correctly. One of the things that worry me is the fact that sometimes I see in my simulation "movements" in the near field that seems to be faster than the speed of wave propagation I defined (the speed of light in the simulation). Specifically I see "nodes" of low amplitude in the E field that are quickly "emitted" from the antenna and then slow down as they approach the far...
