circuit analysis

Hello! I want to automate my Philips 3300 Series LatteGo coffee machine, and ideally without opening it up and voiding warranty. The cheapest, simplest idea seemed to be remotely activating the capacitive touch buttons on the control panel of the machine. It seems remote activation of...

I am creating a video in Manim about basic electrical circuits. The circuit under consideration is an ideal RC circuit with a DC voltage source, no energy losses. My reasoning is as follows: When the current leaves the DC source and flows through the circuit, the capacitor starts charging. At...

Hello everyone, I am currently working on a piezo driver designed for a 2.5nF load with a maximum current ranging between 50 to 100mA with a frequency of 128kHz. Since the load requires a sine wave for operation, I have created a simulation in LTspice using the LTC7060 IC. However, I am facing...

The Question was asked under mesh analysis section. So i Labeled voltage sources and assumed mesh currents. But i dont know what to do with the resulting equations. What am i missing ? I also though of assuming Node Voltages , but ultimately went nowhere as every voltage ends up with 0V...

Hello everyone, I am learning the feedback topologies for 2-port network as we have: -basic amplifier that is represented by 2-port network. -feedback amplifier that is also represented by 2-port network. There is a reference is in the link : feedback topology page 20 and up. My question why on...

Hi. I'm trying to work out how to design a band-boost/band-attenuate filter for an audio equalizer. I've come across what seems to be a pretty good circuit to use in an application note from TI but unless I'm misunderstanding something, the design equations it provides are inconsistent. The app...

Currently stuck on this problem. In class we did not do an example of when the mutually induced inductors were in the same mesh, let alone one the inductors also being shared with another mesh. So I am pretty stumped. I need assistance in coming up with the KVL equation with each mesh. I'm not...

I realized my circuit in Crocodile Clips, but I have some doubts about my circuit. Maybe someone could help me? Please

I'm working on a clap-on clap-off circuit to control two devices: a light and a fan. The goal is to have the following functionality: Single Clap: The light turns on with the first clap. The light turns off with the second clap. Double Clap: The fan turns on with the first double clap. The fan...

Dear Members, I hope you are all doing well. I am a PhD student and completely new to circuit design. I need a compact-sized circuit and prefer not to use an impedance analyzer due to its bulkiness. I am looking to build a circuit capable of automatically measuring the impedance of a sensor in...

Greetings. I'm an electronics hobbyist and I'm currently stuck on Simulating a PCB before Fabrication. I designed a PCB using the EasyEDA.com platform, but I would like to simulate its response before sending it for fabrication. How can I test the PCB, and which platforms/software(s) can I use...

Are those two mosfets still good even if they're burnt transparent? Is that ceramic fuse or is it a chemical directory like diodes and mosfets? I'm in school for electronics but I don't have a multimeter yet to indicate it myself. Can someone please help me identify the three damaged components...

I have a device that works on **3V battery** (2 D size cells) now I want to debug it so that all the devices work correctly. My device consist of **atmega 328p**, running on 08 MHz Crystal which gets readings from ADXL345 for 2 seconds and then store it in 25Q64FVSIG flash memory and then RFM96...

I purchased a 2 sets of hoists that each have a wired and unwired remote. I would like to operate both machines with 1 wired remote and 1 unwired remote by wiring two motors in parallel using a 4 pin wire splitter. The motors operate on a maximum of 10 Amps, I believe the contractors, motor, and...

Hello Community, I am Yogesh D from Trident Pneumatics Private Limited, R&D Innovation - Electronics. We are currently using a 16x2 LCD display (model BCB-1602-03C) in the controllers of our dryers. However, we are encountering significant EMI issues that are affecting the display's...

I want to understand how this circuit works on its several time lapses, we consider the I_s current as constant current: If there is a write-up about this exact version of the chopper can someone refer me to it, instead of writing everything here, infinite thanks!

Let the following circuit: The diodes and SCR are supposed to be ideal, the supply source v(\theta) = V_m \sin(\theta) , let \phi \in (0, \pi) be the angular gate pulse for T1 and \pi + \phi be the angular gate pulse for T2, i want to understand why in the interval \theta \in (0, \phi)...

Here's the circuit from my teacher And here's the circuit i built on ISIS I don't know if i'm using the wrong components or values, i need this for a school work here some more details: 10k Potentiometer Transistor BJT BC547 And i believe most of details are on the image already My...

Hi, how the real power heating current will be a for a pwm signal will be mesured in average? TrueVrms? Or will be the same like normal current. The singal is 0 to 5v. Not negative value, so is more like pulseing dc. For example, two led vf=2v connected to 9v 250ohms with a frequency of 10%hz...

Hi everyone, I watch this video, min 3:30 upward, and it says that the demodulation of AM is when the diode is in the reverse biased but then the current flows!!! isn’t tit the current stop flowing when the diode is reverse biased? Crystal radio circuit analysis/diode demodulation (8-Analog...
