A video made for my GCE A level Electronics students who are familiar with using Circuit Wizard but not CircuitLab. Circuit Wizard is very limited when trying to analyse AC circuits and filters. Although it is possible to vary the input frequency and record the output voltage (and later plot by hand) Circuit Wizard struggles with higher frequencies. If you want to analyse AC circuits then I strongly recommend that you try using CircuitLab instead. CircuitLab allows you to sweep the input frequency and plot the output.

The CircuitLab tool appears to be free when creating circuits on StackExchange (so you may want to explore that route) and you may be prompted to login / pay a subscription to use the software. However, I seemed able to open and modify some circuits for the purpose of this video demonstration. A single user licence costs about $24 per year and I may buy a subscription if there is any interest in school.

Please let me know what you think by posting a comment.
