1. ### Help needed on electronic relay LH1500AT

Hi guys, I was wondering if anyone knows what the DC pin is for and stands for? I've tried to asked Vishay tech support unfortunately there was no reply.... Data sheet can be found here https://www.ortodoxism.ro/datasheets/vishay/83804.pdf Thank you for your help!
2. ### Which output topology is appreciate? class A or class AB ?

Re: Which output topology is appreciate? class A or class AB Why not use an op amp, since you only want unity gain and your load is not big plus its just a lot simpler to build and test.
3. ### Millitary part no. crossreference

Does anyone know how I can find out the equivalent commercial part number of a millitary part number?
4. ### Coupled inductor question

coupled inductor equation Hi everyone, I was wondering if someone could help me figure the state space equation for this circuit, according to the coupled inductor equation V1 = L1 di1/dt - M di2/dt V2 = -M di1/dt + L2 di2/dt which gives me V1 = 1 di1/dt - 1/2 di2/dt V2 =...

two quadrant multiplier Hi echo47, Yes, but if Vc is biased with 0.5V and coupled with an AC signal it would work as a 4 quadrant multiplier? BTW, the frequency response chart in data sheet covers from 1Mhz to 100Mhz. Would this part work for audio frequency if an audio signal is placed at AMP...

four quadrant multiplier Hi Gevy, Thank you so mcuh for your help! The reason I asked is because I am trying to figure out why this part GT4123A is a two-quadrant multiplier, because it seems that IN A, IN B and Vc can all take AC as input? Data sheet click here

2 quadrant multiplier Hi, Can anyone help me understand what is the main difference between a 2 Quadrant and a 4 Quadrant Multiplier? Thanks!

10. ### Another tough 'elementary' question from my tutor

Even though you are not interested in losses but you assumed that V/2 is the steady state of a system with loss, therefore if you do not account for the loss and add that to the system how would you be able to find the steady state of the lossless system?? I suspect that you came to the...
11. ### Another tough 'elementary' question from my tutor

Ok, so if that's the case what is the loss in the system? :D Please include all the mathematical working procedure in finding the loss, as well as how you found the answer V/2 in your reply above. Thanks!

Hi Jasmine_123, Inseatd of solving the assumed lossless system, do you have a solution for NON-lossless system?
13. ### Another tough 'elementary' question from my tutor

Electrical conductivity or specific conductivity is a measure of a material's ability to conduct an electric current. When an electrical potential difference is placed across a conductor, its movable charges flow, giving rise to an electric current. The conductivity σ is defined as the ratio of...
14. ### Another tough 'elementary' question from my tutor

Ideally, the answer should all be the same regardless if its in math or theory. They are just in different "language". Assuming in the case of super conductor, https://www.superconductors.org/terms.htm So because of the nature of SC, the charges can not oscillate as you've proposed in the...
15. ### Another tough 'elementary' question from my tutor

What is this piece of info based on? Can you show some reference? eg. science/physics theory/facts online etc... Or explain why would a bunch of electrons flow as a single entity instead of individual particles? Example There are 2 identical tanks, no.1 filled with water and no.2 is empty...
16. ### Another tough 'elementary' question from my tutor

Why would ALL the electrons pass to the second cap initially? and why would this continue as a sustained oscillation over time and into steady state? What causes the oscillation?
17. ### Another tough 'elementary' question from my tutor

My understanding of the term steady state is that :- "Steady state occurs in a circuit or network when all transients have died away, it is not achieved until some time has elapsed after the system is started or initiated. This intial situation is often identified as a transient state, start-up...
18. ### Another tough 'elementary' question from my tutor

Ok, I think the problem here could be not accounting for the kinetic energy. Total energy = Potential + Kinetic But initially Kinetic energy =0 So Total energy = Potential Energy + 0 = PE IF V=10v C=2F Total energy = Potential + 0 = U = 1/2 * C * V^2 = 100 Total charge Q=C*V = 20C...
19. ### Another tough 'elementary' question from my tutor

Hi, I guess when you said find steady state, you meant final energy in the caps? Does the diagram in the question describes your question? **broken link removed**
20. ### MPLB and ICD2 for testing circuit

Hi Beowolf, Thanks for your quick reply, really appreciate your help! In Jbug11, I can write value to the ports direct eg port address follow by value. What I am trying to find out is the procedure of debuging in MPLB, so very much like the jbug11; in MPLB you just need to write code to set...
