Hi readers, the IN node has triangular wave converted from square wave pulse. This Op-Amp acts as integrator. However, when I attach the same integrator circuit to convert this triangular wave (IN) to sine wave, the Output (OUT) I got is still quite triangular and not quite a good sine wave...

Above is the graph across R7 (Load). Hi readers, Flip Flop with Ne555 timer means turning on an led and another one off, as shown in picture, and this alternate on and off pattern continues. This video can be found at Click Here . I have succeeded in amplifying one of the 2 signal as shown in...

Above is the load power Hi People, I created this npn transistor circuit and it works fine. So basically, it receives this square wave impulse (0 to 2V) and send it to the 10 Ohm(Load) to be amplified to become (0 to 10V). Question: How to simulate the same way (Load Power Output should be...

Hi readers, I am trying to simulate current flow in both direction of the load by using 4 relays or transistors. For example, in this circuit, the load will have left current flow when 2 of the switch or transistors are on and 2 of the switch are off. The opposite way applies too if 2 of the...

To view my We_bench power supply schematic Click here In the picture above, how does the power supply limit its max current and it has been fascinating for me to figure out how. Does anyone have a clue on this? I just know that the capacitor and diode help to rectify the AC output of...

Hi, do the green highlighted pin to connect the main voltage and is the blue one the input switching voltage on the relay? Since there are another 2 pins near the blue highlighted pin, I assume we can connect to either pair right?

If I trap the heat on the hot side of Peltier using a vacuum flask where no heat can escape to the surroundings so that the room can get cooled faster. Would it reduces my Peltier's efficiency and damage it? Or must I remove the heat as much as possible from the hot side to improve its efficiency?

Hi readers, Hairdryers (240V AC) actually works on a design which current passes through the heating filament (Maybe consume 220V) to produce a lot of heat whereas through the DC motor (Maybe consume 20V). I have always been curious about this Question: Hair dryer has an option of choosing the...

I recently bought KSP 2N2222a npn transistors. The picture that I attach below shows the layout. The base of the transistor is applied a 1.5V which turns on the transistors and light up the bulb very brightly. However, I got a bulb that is so dim. The battery power and voltage is fine because I...

Hi. above is a charging cut-off circuit. As you can see in my demo. when voltage source is 5V, the load (R9) has 5W power. When voltage drops to 4V, the load (R9) has 0 W (cut off). However, my lithium ion charging pin for my battery is 4.26V. Thus, when battery fully charged at 4.2V, the...

Hello, I am new to stepper motors and am having a problem. I have a machine that operates in all three directions (X, Y and Z) and has motors. When I do linear movements (one after another) everything goes well I reach a fairly high speed and I am able to lift my load. However, when I want to...

Hi, below is a AC-AC frequency converter with a step down voltage from 200 to 20 Volts Question: As you can see that the efficiency is 1.55/2.251 which is about 66%. May i know how to improve the efficiency of this circuit. I have tried to change the capacitance of capacitor since it...

I want to measure a current consumption for DC fan. I am using OPA2197 opamp for the same. Following is the circuit diagram. i want to understand if this circuit missing anything?

Hello! I have a UNIT-T UT210E clamp meter, which I think it has a problem regarding the current measurements. I will describe the problem below: when I measure current, if the wire is positioned into the center of the clamp (the center marked with the 2 arrows) then it measure 10.16 Aac. But...

Hello everybody! I have two questions. I have this circuit where I want to vary the input voltage (V1) between 0V and 5V to supply power to R2. Is it possible to make the circuit not supply a power (0W) to resistor R2 when my voltage V1 is 0V? When I do the simulation with 0V in V1 there is...

hello everyone, i got a question: I need to make a power supply to heat a heater, for that I need to use an arduino due, and use one of the analog pins (it´s like a built-in DAC) of this microcontroller, and draw voltage from that pin, with an external current source or something similar, I...

HI, I was recently trying to test the capacity of a battery pack I'm building and was trying to measure the current draw using a 35 Turn 540 brushed DC motor (apparently on the website I had purchased from said something about it being sensored, but I couldn't find any sort of sensor inside)...

Hello evryone, I start studying Eletrical and computer engineering and I want to learn thermocouple type k,j etc, however I've been searching and I can find to measure temperatures is using water bath 0° in cold junction so voltage will be the same as thermocouple tables on google, however...

Hi there, I am working on a circuit which would allow me to connect a headphone output to a pc mic input. When asking for advice about the design a question came to mind (thread can be found here if anyone's interested...
