    Buck Converter Efficiency

    The duty cycle is a ratio of output voltage against input voltage. When given an output voltage of 20v and an input voltage of let us say 100 volts then the duty cycle is 20/100.

    Looking for Small Enough Variac

    Check at this variac from digikey 171 Staco Energy Products Company | Test and Measurement | DigiKey I have used it several times in my project for toys. It gives me perfect results and I think it could be helpful to you too.

    battery ratings

    Yes, they both have the same power but one is made of Lead-acid and another one is an AGM type. So from your reply, does it mean that the type of material of the battery has no impact on the battery performance?

    Motor speed control

    Am doing a project where I need to control the speed of the servo, stepper, and dc motors. The dc motor runs a conveyor belt that is being controlled by a timer, the servo motor is moving a cartesian robot along the x y-axis while the servo motor is driving another conveyor belt that is...

    DC Motor controller

    so many options are available and my best and simplest option is building a power supply system that has variable output from 0 to 50 volts. So you need to regulate the voltage from the 240vac to the required variable output.

    Transistor BC547 blowing out

    hello all I have a problem with my PCB board where my BC547 switching transistor is overheating and sometimes blowing out. I don't know what might be the cause because anytime I replace it and I put it on the system for a long time, I find myself in a similar situation where I have to replace...

    How do you connect these battery tabs?

    shrink wrap is for protection against short circuiting of the battery during transport and start of use. You should just remove it and then do the connection.

    NCR18650 Li-ion batteries true manufacturer

    every manufacturer has a trademark and more so today's products have QR scanners to help you scan for original products. I would advise you to buy batteries that have such labels for you to be sure of what you get.

    Capacitors in Series

    let us take note that capacitors are charge banks in the circuits. They store the electric current. We have so many types o capacitors and electrolytic and tantalum are just bust a few types. This capacitors have different leakage current effects and the behavior of the capacitors is determined...

    LFP batteries Ampere-hour comparison

    the two batteries' performances will depend on the amount of current you drain on each of them. If the current you are draining is the same, then battery one will lust at least 9 more hours than battery two ie when you use a constant current load. the A-h is the most important characteristic in...
