voltage

Hello I have got one last confusion about charge controllers doesn't matter whether it is pwm or mppt. Thing is i have seen many CC with variety of output amps on 12v and 24v with different manufacturers... But they are all different.. Which number in a charge controller defines that how many...

Hello My question might seem very obvious but i never really understood why... Too much power is being wasted during charging because of this internal resistance, there must be a logical explanation for this and i need that to know. I am not looking for technical answer instead if you could...

Hello As the title says i need to know what should i buy? which one would give me the most accurate reading? I want to know how much power my appliances consumes, tv, washing machine etc.... Also i need to buy a new ups for my PC so just wants to know how much power my pc eats. I have a 500W...

Hi guys! I'm trying to build a device to measure the electrical resistivity of a paste (cementitious materials) using Arduino Uno. Four steel probes are put inside the paste (jumper wires attached to them). Two outer probes apply AC signals (Square wave signals- Frequency 1 kHz- Voltage(peak to...

Hey guys, This is my first post and I am happy to have found this website. I am currently working on a project using a PCB and jumper wires to make a 48v Phantom Power supply to be used with multiple condenser microphones. To make a long story short, I found a "mostly" detailed post on another...

Hey guys. I'm designing a series pass voltage regulator with feedback. I'm trying to disconnect the load when the load current or control element temperature exceeds a value. The attached photos show my circuit design. The temperature cutoff circuit works as is, but the current cutoff does...

Hi there, I'm curius. Do varicaps exist, that can operate with mV or even µV? And what should I search for? Thank you and best regards, Moritz

I am trying to control voltage range from 1.5 to 34 using LM338 voltage regulator with 1000u capacitor at the input 430u capacitor at the output with potentiometer @ the adjustment terminal. I have 37v and around 5 Amps current at the Vout but when i try to reduce the voltage using...
