Hi, I am new to electronics and I am a final year undergraduate from the UK. I have a project I am currently working on. the project is to design, build, measure, and compare a Class A and a Class ...
We have to maintain the focus of the Electrical Engineering board at the electrical engineering level. We will be inundated by laymen questions (electronics use, repair, explaining electronics to ...
Thanks for asking. Repair questions are off-topic, in general. We may consider a repair question, if you explain your specific troubleshooting steps, and you understand the design of the device....
Moderator's note: This is getting ridiculous. You keep posting these drawings that are barely legible. The scribbling is bad enough, but the uncropped images are unacceptable. The image you ori...
We identify semiconducting electrical components this way: The first digit represents the number of pn junctions inside the semiconducting device The two or more digit number starting at position...
My mistake was taking the third relationship $$ \frac{1}{RC} $$ which says how to find the bandwidth of a parallel RLC filter but we have a series RLC filter. Now solving the system : $$ LC = 100...
Instead of using a buck or a boost converter can we use for DC-DC conversion the circuit Im going to describe in the next lines? First we begin with a Hartley oscillator whose output is fed into ...
Im studying the equivalent model of a BJT common emitter amplifier at high frequencies.At university we tought that the BJT at high frequencies looks something like this: However when designing ...
Design a suitable experiment and an AC circuit to verify Thevenin's theorem when the load is a single-phase induction motor with a capacitive start and two supplies feed the load. Ratings of load:...
what diffrence between tesla and edison? can anyone help me who come first?
On the LEFT is what I just bought today — Globe Electric 4W (40W Equivalent) Daylight (5000K) Dimmable LED Light Bulb, G9 Bi-Pin Base, 400 Lumens, 15,000 H. Here's Globe Electric's Dimmer Compatibi...
Which capacitors have smaller self resonance frequency?I would bet my money on electrolytic capacitors because they are usually much bigger than the ceramic capacitors however I don't know if they...
Before the circuit here are the digital blocks which have been already designed and exist as part of the division block 1 bit subtractor: 2 bit subtractor(in the digital block diagram of the di...
This question may be only for @Olin Lathrop but I would like to hear others opinion When I had asked the question he just said that "What's the question?"- 'This "question" is just lecturing on co...
I have decided to try design a band-pass filter with a cut-off frequency of 10kHz and bandwidth of 2 Hz. $$ \frac{1}{\sqrt{LC}} = 10001 \rightarrow LC = 1/100020001 sec^{2}$$ $$ \frac{R}{L} = 2...
I HAVE A METER LIKE THIS BEHIND MY HOUSE MY NEIGBOR SLOWED IT DOWN SOMEHOW HE SAID HE OPENED IT UP AND DID SOMETHING TO IT NOW HE PAYS LOWER ELECTRICAL BILLS THAN ME BUT HE HAS COLLEGE DEGREE IN ...
