Ratings and reviews

I like it a lot however..... What it needs to do is update the graphics based on the variables. For example resistors in parallel. As you increase the number of parallel resistors update the graphic to represent the same.

its a bit simple, can certainly use some work but overall useful if you know what you're doing. would be useful if there was a way to insert an output like you can the other variables. such as an input field for time with the 555 timer. id also suggest showing the equations that are being used so that one can understand what is happening and why.

if the scaling improves, the rating will too. very bad graphic experience. fields are off screen & cut off. otherwise it does the calculations as advertised
