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 … ...

In the last Circuit VR we looked at some basic op amp circuits in a simulator, including the non-inverting amplifier. Sometimes you want an amplifier that inverts the signal. That is a 5V input res… ...

How damaging is EMI to op amps in a circuit design? And what methods are used to minimize these effects? Circuit designers may be surprised at the clever ways op amps can be used ...

When it comes to electrical circuits, there’s a lot to remember and understand. We've got you covered with this Intro to Circuits BBC Bitesize guide.
