A voltage divider is a passive linear circuit used to create a voltage less than or equal to the input voltage. It is a conversion device composed of a high-voltage arm and a low-voltage arm. The ...

Find the voltage v1 and the currents I1 and I2 for the circuit shown. To solve this problem first find the total current going through the 14 ohm resistor. To do this find the effective resistance of ...

Andy recommends favorite resources for basic op amp circuits and includes a portion of TI's AN-20. Test your knowledge with our op amp quiz; answer explanations are included. By 1969, a fledgling ...

Image depicts a de-energized controlled environment with no chance for arc flash. Will this quiz on low-voltage circuit breakers trip you up? Give it a go and find out. You will be shown the correct ...

What are HVICs? High-voltage integrated circuits (HVICs) translate low-voltage control signals to levels that are suitable for driving power switches in high-voltage applications. HVICs also can ...

When you determine conductor sizes for low-voltage feeder or branch circuits, do you account for voltage drop? Some people believe this is unnecessary, and some believe that doing so is a Code ...

I see techs in the field get the most frustrated when they have a low-voltage short they can’t seem to locate. The challenge techs face with low voltage diagnosis is a combination of poor process and ...

Circuit simulations are great because you can experiment with circuits and make changes with almost no effort. In Circuit VR, we look at circuits using a simulator to do experiments without having to ...
