Circuit Simulator]. (Sorry for the bad quality screenshots)
Step 1: Basic controls
When the program is opened on the screen, the buttons on the toolbar are:
File - Import, Export, Exit
Scope - Stack All, Unstack All
Options - Show Current, Show Voltage, Show Power, Show Values, Small Grid, European Resistors, White Background, Conventional Current Motion
And finally, Circuits - To list all of the seperate circuits would be quite pointless as there are loads of them (See for yourself if you dont believe me!) These circuits come with the program that the creator must have pre-programmed in.
